10.Alvaro Morata-Forward
It has been a frustrating season for Morata since his move to Chelsea and has failed to find his feet, netting just 11 Premier League goals in 31 games. However, he has a good history of scoring for Spain, having netted 12 goals in 17 appearances in 2016 and 2017, including three goals at the Euros. But this has not guaranteed him a place in Russia, with the likes of former Real Madrid team-mates Isco and Marco Asensio plus ex-Chelsea striker Diego Costa preferred instead.
