Swap deal with Cerci, the latter hasn't been any more useful to them than Torres would be tbh. Besides, if there was someone who could get the best out of Torres (or what's left of him) it'd be Simeone. I think he'd do better with a striking partner than as a lone #9 anyway. The only downside for Atletico is wages, Torres should definitely take a pay cut if he has any respect for his old club taking him in.
