Roberto Martinez described Ross Barkley as a footballing "diamond" after the midfielder further enhanced his ever-growing reputation by scoring a stunning winner in Everton's 2-1 win at Swansea.

Seamus Coleman had given the visitors a 66th-minute lead with a ferocious strike, but they were pegged back when Bryan Oviedo put Dwight Tiendalli's off-target effort into his own net.
Everton were not to be denied as Barkley stepped up with six minutes to up to beat Gerhard Tremmel with a free-kick which nicked the underside of the crossbar on its way in.
The goal, and another fine individual performance, will ensure the 20-year-old will again be in the headlines after a string of excellent recent displays, and it is hard to see how Roy Hodgson can leave him out of England's World Cup squad.
The win moves Everton up to fourth in the Barclays Premier League table, just two points behind leaders Arsenal, who play Chelsea on Monday night.
And Martinez was left to heap more praise on his midfield starlet.
"Ross is growing game-by-game. He is showing different aspects of his play, he is a quite incredible diamond of English football," said the Everton manager.
"The winning goal, technically, is as good as it gets. A lot has been said about Ross, but it's always an understatement.
"He's an incredible listener and young man with a lot of potential. He always comes up with something different in a game to show he can develop.
"I'm proud of seeing him grow.
"You could see he was fighting with Romelu because Romelu really practices his free-kicks.
"But Ross is a player who gets fed by feelings. He's a natural talent who can play in any position.
"We didn't know he could take free-kicks, but it's good to know from now on."
Everton thoroughly merited their success, which tees up back-to-back home games against Sunderland and Southampton.
Although the Merseysiders were not at their best, they still created the majority of the significant chances.
And Martinez felt the win at one of his former clubs was as satisfying as any win during a season which has also included successes against Chelsea and Manchester United.
"We had three difficult away games. At Old Trafford, the Emirates and the Liberty and this was the biggest test," he said.
"It's easy to keep your concentration levels when you go to the other two, but unless you are 100 per cent when you haven't got the ball, this Swansea side will punish you.
"I couldn't be happier. We weren't at our best, but we kept Swansea quiet. We conceded a soft goal by our standards, but we had the desire and our determination to want to win the game was pleasing.
"It's the best satisfaction of the season."
Martinez was also confident the problem which saw Steven Pienaar limp off late in the game will not keep the South African out of the Boxing Day meeting with Sunderland.
Meanwhile Barkley admitted he knew he was going to score his free kick.
"It's a relief because I had a chance to score with 20 minutes to go and I slipped, so to see the free-kick go in was a bonus and great for the team," he told Sky Sports 1.
"I told Romelu Lukaku to leave it, because I saw the goal and thought 'I'm going to score this'.
"I don't really practice free-kicks because Leighton Baines is usually on the pitch, so I thought it was my chance."
Skipper Phil Jagielka was happy that Barkley was on his side.
"He slipped and thought it wasn't his day, then five minutes later he hits the bar. Then he's brave enough to take the free-kick and he did," he said.
"It's a massive result because everyone around us won. It was a big game for us, we might have been fortunate to take all three points but that's the sign of a good team."
Swansea boss Michael Laudrup agreed with Jagielka. "We did not deserve to lose, conceding such a late goal at a moment when Everton, I think, were okay with a draw.
"It was harsh and the least we deserved was a point. That's how football is. Their goalkeeper made a couple of great saves. I don't want to say Everton found luck, because it was a great free-kick, but they found the three points.
"We did well, we played against one of the most in-form teams in the league. We have to move on, the games will come in three days."
Swansea manager Michael Laudrup felt his side should have got something from the game.
"I think we deserved more," he said. "The first half was tight, there were not many chances but they came out second half and went in front with a strike from distance.
"We fought back as we really wanted something out of this game but the thing that is most disappointing is I thought in the last 10 minutes they were happy to take a point.
"We were still pushing to get a winner and then they got it from a free-kick.
"But we have to accept it."
Laudrup also had praise for Barkley. "He is a great talent, he is a great runner with the ball, he can play in tight areas, he is definitely a big talent.
"He already has a lot of talents for someone so young."
Laudrup confirmed Swansea are set to make a decision on whether Michu undergoes surgery on an ankle injury.
"We will know more tomorrow," he said. "He may have a chance for Boxing Day but we will see, we will have a final opinion from an expert and then decide.
"If tomorrow the information suggests he needs an operation he will have surgery in the very near future.
"Obviously we are not happy he could be out for several weeks, but the most disappointed person is Michu.
"If it is bad news tomorrow, added to what happened to Nathan Dyer last week, we will have to think about what to do in January."
