I think we should be smarter than that with our choices to minimise the risk. Any manager will need a new GK, and we should be looking to buy younger players who are not system specific.
Younger players that Conte will rush to tell the press are "club buys"?
The reality is the GK situation is probably a summer resolution, with Conte we need a RWB, without him we need a creative midfielder, with Conte we need a CB for the center of a 3, without him it's highly likely we are looking for a CB that can play on the left of a pair (alongside Romero), with Conte we need to build to a front 3, without him? with Conte players like Gil, Sarr, Spence, White probably need loans, without him you probably could integrate 2.
It's almost impossible to make decisions here without understanding if Conte will be here next season (not just to the end of this one)
