The Argentine youngster curled his finish home after receiving a stray ball inside the Hammers' area.Fred sealed the win with his strike late in injury time. The Brazilian midfielder now has eight goal contributions in his last 11 games across competitions.

Right after the win in the Carabao Cup final, the Red Devils had to quickly shift their attention to the FA Cup.Ten Hag was quizzed about the quick turnaround ahead of the West Ham game. The Dutch manager replied (via United's website):“It’s our job; it is their job, so we don’t allow them to stay in the mood from Sunday. Sunday is history. It’s nice, memories, but if you want to perform, you have to focus on the things you have to do. You have to focus on the job.”The FA Cup is another competition Ten Hag's side have a chance of winning this season. They are also alive in the UEFA Europa League and trail Premier League leaders Arsenal by 11 points but have a game in hand.
