England's friendly with Nigeria could give us some clues to Gareth Southgate's World Cup starting XI against Tunisia - we look at his likely options.
These two Group G opponents kick-off their campaign in Volgograd on June 18.
With a few names in Gareth Southgate’s line-up seemingly set in stone, we look at the different approaches the England boss might take when it comes to those more contested positions.
The most likely starting XI combination comprises of what looks like a back-five system that utilises two deep-lying central midfielders and two more attacking threats in behind the striker.
Billy Cundall takes a look at Sky Bet's odds on the market...
Line-up: Pickford, Trippier, Walker, Maguire, Stones, Rose, Henderson, Dier, Sterling, Alli and Kane
There is no surprise to see newly-installed captain Harry Kane start up-top, supported by two creative flair players in Raheem Sterling and Dele Alli. Jordan Henderson and Eric Dier provide a solid foundation in the midfield, allowing the two pacey wing-backs to patrol the wide areas, aiming to supply the Tottenham star up-front.
Line-up: Pickford, Trippier, Walker, Maguire, Stones, Rose, Henderson, Dier, Sterling, Lingard and Kane
In the same formation, this line-up changes where we see Manchester United’s Jesse Lingard replace Tottenham’s Alli.
Alli’s talent and ability to flip a game on its head is undoubted, but Lingard’s ability to utilise one-touch passing to transition the game from the midfield into attack has drawn plaudits this season, with ex-England captain Rio Ferdinand recently echoing the view that the United man should be in the starting XI.
It remains to be seen which player Southgate prefers, and the two upcoming friendlies should provide a good indication of his intentions.
Line-up: Pickford, Trippier, Walker, Maguire, Stones, Rose, Henderson, Alli, Sterling, Lingard & Kane
If, like me, you are wishing you could include both, then maybe this line-up is for you.
Southgate could opt to trust Liverpool captain Jordan Henderson to patrol the midfield solo, meaning there would be no place for Spurs utility man Dier.
Dier’s void would be filled with the inclusion of both Alli and Lingard. A bold strategy, but one that would be sure to provide excitement when England bring the ball forward.
Line-up: Pickford, Trippier, Walker, Maguire, Stones, Young, Henderson, Dier, Sterling, Alli and Kane
In a similar line-up to the first, this one sees Spurs full-back Danny Rose lose his place to a surprise performer. After emerging from what seemed like the abyss, Ashley Young’s displays for Manchester United have not gone unnoticed, and this line-up rewards the 32-year-old by granting him a starting place versus Tunisia.
Line-up: Pickford, Walker, Maguire, Stones, Jones, Rose, Henderson, Dier, Sterling, Alli and Kane
Phil Jones finds himself amongst the starters in this 16/1 shot. Despite Kieran Trippier’s strong performances for Spurs this term, Southgate might not trust Walker at centre-back just yet, and his pace and power could be desirable at right wing-back instead. In this case, Trippier would make way for Man United’s more recognised centre-half in Jones.
Line-up: Pickford, Trippier, Walker, Maguire, Stones, Rose, Henderson, Dier, Sterling, Vardy & Kane all to start
Jamie Vardy producing another Premier League haul of 20 goals must have given the Three Lions’ manager a headache. The forward proved again this season that he is cool and clinical in front of goal, and will be sure to stake a huge claim to start in Russia.
The Leicester man proved to be an influential figure in France at Euro 2016, scoring a vital goal against Wales in the group stage, and the calls for him to start in Volgograd are becoming louder and louder.
Kane and Vardy boast an impressive 50 Premier League goals between them this season, and a flourishing partnership could be England’s best chance to scare even the best of defences.
Attacking influence Alli would miss out, but perhaps Vardy’s noise is too loud for Southgate to ignore.
With three weeks until the World Cup kicks off, not even Southgate can be sure of his starting XI, and with twists and turns sure to be along the way, who knows who will be lining up in a Three Lions jersey for the opening game.
