Oh without doubt, selling young players for big money is a good ploy, and lets face it he is very sellable. I think the club and the market probably felt to get to a say £70m valuation they needed another consistent year from him. I do wonder if the madness of this summer, and particularly the last few weeks has blown that open though, and they feel their could be a big offer coming. I don't think we would ever be in the position to turn it down, but we certainly aren't currently.
United have just paid 75m for a striker who scored 9 goals last season. It's just crazy season, and probably why the club is sensible targetting other young players who they could slip.
The thing with Onana is as well, like if he went, we are not desparate for a replacement either. Garner, Gana could play in there, Doucoure could drop back and you could shift Iwobi inside. So you have 4 options for 2 positions. At a push Godfrey could fill in. I'm not saying we don't sign anyone, but we are probably best covered for that position.
