Manchester United and West Ham start their new Premier League campaign at Old Trafford on Sunday.
The Red Devils have signed Romelu Lukaku, Victor Lindelof and Nemanja Matic, and manager Jose Mourinho knows the United faithful will be hoping for nothing less than a title challenge in his second season as boss.
While Slaven Bilic will be looking to make his West Ham side a tough and consistent team this season. The Hammers will be hoping to upset the Reds at the Theatre of Dreams after Mourinho said the east London club's impressive transfer business makes them potential title rivals.
Javier Hernandez has joined Marko Arnautovic, Joe Hart, Pablo Zalabeta and Sead Haksabanovic at the London Stadium, and the tie against United on Sunday will be a real test of how far Bilic's men have come in a short space of time.
