Manchester United shot stopper Andre Onana has been given some advice by a sports psychologist.
The Red Devils brought in the Cameroonian to improve their passing from out the back.
However, Onana has struggled with the basic tasks of goalkeeping, while United have lost six of their first 11 games this season.
It makes a massive difference," Dr Josie Perry told The Mirror.
The culture of each club is different. The style of play they expect, the management style all the little nuances: what time you train, when you eat, the S&C, how you're expected to do things."
Often you will never be able to fully prepare for it," Dr Perry added.
Often it's about being able to take what happens and be willing to learn. That's difficult when you also really need to impress. If what you've got in your head is 'I must impress, I must win, I must do X, Y and Z' while you're also trying to learn and get to grips with things and how things work, that's very tricky."
