As our current forwards are Kane, Son, Richarlison, Kulusevski (4 players) with Moura (not that useful ) and Gil (not that trusted, can be knocked off ball) I think we were finding ourselves a little short of quality alternatives even before Richarlison, Kulusevski and now Son injuries,
IMO the RW creative position is the one position where we are one player short of a quality alternative which is really hurting us now. Hence if Conte thinks 29yearold Malinovsky is the best option available and wants him, I'd take him.
In other parts of the squad, if we can upgrade with an available quality player in January, we can do it or wait until summer. I think waiting for the RW until summer is too risky.
