Even if Inter don't drop down from 60 million euros I don't think Manchester United will back down from the deal. Because Onana might really be the best option available in the transfer market now. They can't sign a random goalkeeper after having a wonderful one for 12 years like De Gea. They should be able to keep their defending reliable for bigger successes.
Indeed, on the other hand, this is the main thing that Ten Hag has to think about, De Gea has been able to become a stronghold for Manchester United for many years, and with De Gea Ten Hag's departure, he must think about a suitable candidate who has the performance of De Gea or even more. I'm sure there is no other alternative that Ten Hag wants other than Onana because I know he believes in him a lot and recently I heard in the news that now sheik Jassim has managed to acquire Manchester United from the Glazers family. If this is true then this is great news for the Red Devils squad because with the arrival of sheik jassim as new owner, I believe Ten Hag will have a better chance of signing some quality players in the transfer market including Onana.
Manchester United are very interested in Onana, especially since they have decided to release their main goalkeeper David De Gea, so Manchester United must be able to get a suitable replacement. Onana is indeed very good, so it is only natural that Inter Milan holds him at a high price because it is quite worth it with quality. which is owned by the players especially Onana is also still very young.
But on the other hand, I really doubt the Manchester United team's decision not to renew De Gea's contract, even though so far De Gea's performance is still very good and even last season his performance was still very good.
