#4 Jack Wilshere

In a huge blow ahead of the World Cup, Jack Wilshere will be missing England's friendlies. His fitness has drastically improved this season, so it is a major upset that he will have to miss the friendlies despite receiving a call-up from Southgate.
This threatens Wilshere's chance of representing England and the remaining games that he will play for Arsenal will be vital in the selection process. A bright talent for Arsenal and England, Wilshere has illustrated his capabilities whenever possible, especially in the Europa League.
It is a joy to see Wilshere play but the chances of him wearing the England shirt in Russia this summer are slim. There is a chance that he could be called on board if Southgate trusts Wilshere, though.
