#4 Wayne Rooney
Rooney is finally back home after achieving all he could with Manchester United. Many see his transfer as a retirement move, but Everton fans and Ronald Koeman would feel otherwise. Everton are now a very ambitious club, with fans that ask more and more of their team as seasons pass.
Besides the expectation at club-level, the coming season is also a World Cup year and Rooney will have every intention of making the squad that travels to Russia. If he cannot perform for his club, there is no chance that Southgate would take a chance on the veteran.
The Englishman has a lot to prove to the Everton faithful who were unhappy when he left the club for United, and they will not accept anything less than his best. Rooney himself has stated that he is there to win trophies, and if he does not perform, he could see his homecoming cut short, resulting in him sitting at home to watch the World Cup.
