The Spaniard’s contract with Manchester United expires on June 30.
Although the goalkeeper has reportedly agreed a two-year extension with the Red Devils, both parties are yet to put pen on the renewal documents.
Hence, United are looking at options, and according to The Athletic, they have zeroed in on the 27-year-old Onana.
United manager Erik ten Hag is believed to be an admirer of Onana, having worked previously with him during his stint at Ajax.
The keeper is confident with the ball at his feet, and his distribution makes him an ideal candidate, confident enough to play out from the back.
However, the shot-stopper will not come cheap, as he has a contract with the Nerazzurri until 2027, and the Serie A side will likely demand £70m in transfer fees.

If De Gea departs the team, United might make an all-out effort to sign Onana.
Also, Dean Henderson might be sent to Nottingham Forest if he remains, but if he doesn’t, the Tricky Trees are ready to make a formal offer as soon as they have further information.
Then, Manchester United would like to acquire a back-up custodian, and Burnley and Brighton have both expressed interest in Bart Verbruggen of Anderlecht.
