Yes, if we think like that. But we're talking about Zouma possibly loaned out here for whatever reason and also it is happened in winter transfer window. First, Zouma is U21, and we must replace him with another U21 one, because our non HG quota is full. Kalas is the best choice imo, or do you have any better option U21 player? Second, I don't think it is wise decision to buy anyone in January, for Zouma replacement. The price will be sky high, and I doubt the player want to join, knowing that they will be on the bench most of the time, behind Terry and Cahill.
