Diogo Costa has been eyed by Manchester United as a potential replacement for Andre Onana if he leaves. Costa has also been eyed by Chelsea, but remains on United's list as a priority.

Manchester United is interested in Diogo Costa, especially with the anticipated arrival of Rúben Amorim as manager. There is uncertainty whether United will replace their current goalkeeper, André Onana, with Costa.

Manchester United considered signing Diogo Costa last autumn due to dissatisfaction with André Onana's performances.

Costa was previously of interest to Manchester United in 2023 as they weighed up potential replacements for David de Gea before formally pursuing Andre Onana.
