England will officially begin their World Cup preparations on Friday when they host Chile in a friendly at Wembley.

Here, we look at the key battles which could decide the outcome of the encounter.

PHIL JONES v ALEXIS SANCHEZ

Fabio Capello compared Jones to Franco Baresi after granting the then 19-year-old his international debut, but Roy Hodgson did not start the versatile player once in the World Cup qualification campaign. Jones will get an opportunity to impress on Friday, however, when he is deployed in his favoured position of centre-back. Sanchez grew up on the mean streets of Tocopilla, but now he is the biggest star in Chilean football following his big-money move to Barcelona. Sanchez often drifts out wide and then cuts back in off the right flank, so Jones will have to be at his best to keep the pacy forward out.

ROSS BARKLEY v MARCELO DIAZ

With just three matches to go until England's provisional World Cup squad is announced, Barkley will be keen to put in a top performance on his full debut. The 19-year-old Evertonian is capable of linking midfield and attack with surging runs and he also has a keen eye for a pass. Diaz, 26, has been a key cog in Basel's recent success. The combative midfielder moved from Universidad de Chile in 2012. His bruising performances were key in Basel's run to the semi-finals of the Europa League and he will be the man to tackle Barkley along with Charles Aranguiz.

WAYNE ROONEY v GARY MEDEL

With Rooney's tendency to drop a little deeper to pick up the ball, Chile's defensive midfielder Gary Medel, known as 'The Pitbull', will be given the task to muzzle the striker. Medel has been a revelation since moving to Cardiff from Sevilla for £11million last summer. He gained his nickname after a series of combative displays in his homeland and at Sevilla, where he was sent off seven times in 90 games.
