I think we are doing OK here...
KDB Gundo contracts expire this summer
Walker Bernie contracts expire next summer...
Plus we have one player who has to prove his worth in Matheus and academy graduate Macatee.
So I guess this summer we will concentrate on KDB & Gundo replacements, which means that we will buy defensive midfielder who covers for Rodri and either Matheus proves his worth as an attacking midfielder or we will sell him, add extra money and buy player like Wirtz or Musiala or whoever they are talking about.
Then we will have to replace Walker & Bernardo. By that time hopefully Rico will be fully ready for the first squad and we will buy his cover or competition, like Frimpong for example. As for the Bernardo, we will have 2 full seasons of Macatee by then and if he proves worth, we will use him as Bernardo's successor, otherwise same will happen to him like it happens to Matheus.
Therefore next two summers: 1 CDM and 1 RB. Plus 2 CAMs depending on Macatee / Matheus situations, which means that at least we will generate 50% of those transfers by selling Macatee and Matheus.
After two years, we will have to look at CB replacements, but till that happens, we will have a lot of time..
In other words - well done Txiki.
