So can Torres play for Barcelona straight away?
No, not unless the club lowers its own costs, due to LaLiga's financial rules. As things stand the club are still outside of the Spanish league's spending limits and are therefore subject to the 1:4 ratio - if they want to bring in a player on a €4m (3.4m) salary, someone on €16m (13.8m) needs to leave, for example.
The Barcelona board are going to have negotiate more pay cuts if they wish to see Torres on the pitch in 2022. Aguero reportedly agreeing to forego the second year of his contract and only collecting part of his wage for the remainder of this season is a start.
