Ruben Amorim, the new manager, is expected to have a tight budget, which means Onana, the 29-year-old Cameroon international, might stay put for the time being. Onana has had a rocky start to the season, with costly errors, notably in their Europa League quarter-final first leg against Lyon.

However, if United receives a £20 million offer for Onana, the plan could change. The keeper is reportedly being courted by clubs in the Saudi Pro League, but no official moves have been made yet.
