Onana does look like he would worth about 40 max 50 million to be fair, I do not think that the offer is too bad. What are they expecting for Onana? 100 million? Lol, that's the amount of money you could expect for a decent goalkeeper these days and not a lot more and even all over online, the worth for him is about 35 to 40 million range so the offer is not bad at all.
That offer was not bad but inter wants more. Inter asks €60 millions for onana. Inter was also giving deadling 20 july as the late day to determine onana's future. The problem is, al nassr and several clubs from EPL other than MU linked to the onana. That push inter to put a high price on him. It consider his performance last season which was quite good to brough inter to the final of UCL..
I understand Inter doesn't need to sell, they can just keep him, and when you are not willing to sell then it becomes a lot harder to buy that player for anyone else. However, it looks obvious that we are going to end up with a situation where they are going to provide some more money. I would say offer 50 million straight up, and do not offer a dime more, he won't worth more than that at all.
MU has an alternative for onana. Onana was a priority, but it doesn't mean MU shall only focus on him.
I prefer to see MU get one from these keepers, Justin Bijlow or Kevin Trapp.
