Chelsea v Tottenham Hotspur: Our prediction
David John says: Spurs have definitely parked their tanks on the Chelsea lawn over the past fortnight and the spin doctors are advertising Saturday afternoon’s showdown as some sort of Premier League title decider.
Chelsea’s Gary Cahill was first out of the blocks as he desperately tried to play down the significance in the longer term of facing their fast-finishing rivals in the top flight.
Tottenham striker Harry Kane responded with the theory a victory here could have a significant psychological effect over the closing six games in a build-up where we all seem to have lost track of the fact there is actually an important Cup semi-final buried somewhere in amongst all the posturing.
Whatever the subsequent fallout, Saturday’s game has a beguiling quality coming in the midst of Antonio Conte’s stickiest spell as Chelsea boss while Tottenham stage a late-season blitzkrieg that stands at eight wins on the bounce.
Punters seem to be keeping faith with the Blues though as the market starts to take shape with them narrow favourites to win in 90 minutes and a fraction of odds-on to qualify for next month’s final.
That support suggests the team that has been the best in England for 4/5ths of the season will bounce back with gusto following a 2-0 defeat last weekend against Manchester United.
The excuses for a very lame effort at Old Trafford have poured out from the Chelsea camp – Conte blamed himself for not motivating his team enough. Officials blamed a bug affecting some of the squad. Players blamed a rare off day. Thibaut Courtois blamed the NBA.
The performance smacked of being outwitted by ex-boss Jose Mourinho mixed in with a case of good old fashion nerves after Tottenham had cut the deficit at the top to a very manageable four points 24 hours earlier.
They could not fashion a chance on target, Eden Hazard barely got a sniff, N'Golo Kante lacked his usual influence and Diego Costa returned to the narky, irritable character of last season as his domestic goal drought now tallies six games.
Conte might imitate a whirling dervish at times on the touchline but he strikes me as man who will not resort to bouts of panic – a lot of fuss surrounded Chelsea’s defeat to Crystal Palace but the Italian steadied the ship as his side immediately delivered big victories over Manchester City and Bournemouth.
He is going to have to really dig deep once more against the one side that has not chucked in the towel against them this season and played them off the park at White Hart Lane in early January with a thoroughly convincing performance.
There have been few setbacks since for Mauricio Pochettino’s men outside of a ropey Europa League effort and they seem to be making a perfectly timed run on the two competitive fronts remaining.
Confidence is sky high and reflected in an attacking verve that has seen them average over three goals per game during the current winning streak while the defence has not lost any of its miserly qualities.
Perhaps this season all the little things might be falling in their favour as well.
Kane’s ankle injury sustained against Millwall healed much quicker than expected and he is back in the goals although the versatility and dedication of this group of players covered his absence in ample fashion.
Dele Alli, Christian Eriksen, Son Heung-Min and Mousa Dembele are an embarrassment of riches at the peak of their powers for Pochettino in midfield and man for man at the moment, this is a team that are a match for anyone in the country.
Perhaps the only thing left to conquer is the strange recent affliction developed playing at Wembley but it is not possible to hold some trivial mental block against a group this good for too long.
It is hard to believe Tottenham are the underdogs and I think it is going to be tough for Chelsea with those few creeping doubts to stop the current momentum of their rivals.
How the rest of the season will play out on the back of this fixture is a debate for another day but I am very keen on Spurs ensuring they are coming back here on May 27.
Prediction: Tottenham 3-1 Chelsea

Erik Lamela and Harry Winks are both out with hip and ankle injuries respectively while goalkeeper Michel Vorm is also unavailable with a knee problem.
Chelsea (from): Courtois, Begovic, Fabregas, Zouma, Alonso, Kante, Hazard, Loftus-Cheek, Moses, Pedro, Costa, Matic, Willian, Batshuayi, Terry, Azpilicueta, Chalobah, Luiz, Eduardo, Aina, Ake.

Chelsea v Tottenham Hotspur: Manager quotes
Antonio Conte (Chelsea)
On Tottenham: "There is a moment you have to finish considering yourself an underdog. I think this is the right moment.
"Tottenham now is a really great power in English football. This is the third year for them (under Pochettino) and I think it's the right moment to finish (talking about being) considered (an) underdog and to find his excuse."
On whether the FA Cup clash will have an impact on the Premier League run-in: "I don't think if one team wins or loses it can affect the other competition."
On Gary Cahill's availability: "Our doctor preferred to bring him to the hospital and to check his condition,.
"Not a serious problem, but now Gary is getting better and is improving a lot."
"If you ask me for tomorrow, my answer is it is very difficult."
On John Terry's departure: "If you ask me is he a serious loss for next season? Yes, I think so.
"The problem is that John wants to play regularly and for this reason I think that we have to respect his decision."
Mauricio Pochettino (Tottenham)
On whether Spurs need silverware to be successful: "Here is a massive success.
"Yes, you can win titles. But with which teams? It is normal to win titles with Barcelona, Real Madrid, Bayern Munich, maybe Juventus, Porto in Portugal.
"With a big team, you are already very close to winning. Look at Barcelona with Pep (Guardiola), with Tito Vilanova, with (Frank) Rijkaard, with Luis Enrique. All different managers but with the same group of players and they were successful.
"Success for me is to finish in the top four like last season. It was a big success for Tottenham and means maybe more than winning one title with Barcelona.
"I dream of lifting trophies but the way I did with Espanyol, two Copa del Reys with Espanyol, that is why I admire Diego Simeone at Atletico Madrid. It is so difficult to win with Atletico Madrid. He deserves more credit maybe than some others."
On being ahead of schedule: "I think the process when we started three years ago, was the club creating new facilities, a new stadium, that was the plan and the team was here too.
"But it's true that the step was massive from the team, while the club is still growing up, but not in the same pace. And now maybe we need to wait a little bit for the club to arrive - to finish the new stadium, to move from Wembley to White Hart Lane again.
"And that moment will be the moment to push and try to win. But, if this season we can win, or next season we can win some titles, it's welcome."
On backing up last season's efforts: "We are, over two seasons, the best or the more consistent.
"We are showing that we are a team that you can trust. It is another thing to take 100 points and win the Premier League, and then another season to take 40 or 45 points and be fighting in the middle of the table."

Chelsea v Tottenham Hotspur: Sky Bet odds
Sky Bet find it almost impossible to pick a favourite for the first FA Cup semi-final, with Chelsea marginally shorter odds at 13/8 to win in 90 minutes and 10/11 to make the final.
