Of course, if Manchester United can sign him, they'll fill a significant gap, because we've seen since last year that one of Manchester United's weakest areas is goalkeeping. Andre Onana isn't a good enough player in that area. He was actually transferred for a substantial fee, but last year was a complete disappointment. If Gianliugi Donnarumma chooses Manchester United, Manchester United won't have a goalkeeper problem for long.
I will be really glad to see him at Manchester United because that is where he is needed the most because PSG appears like they no longer need him so it will be best of he goes where he will be needed and I also think even onana will do better elsewhere, Manchester United may be too big for him, the pressure he gets may be affecting him but outside Premier league where the pressure may be lesser it is possible he may do better so I will love that Manchester United gets the deal done to get Donnaramma
