Torreira is not better than Gana, nor could him being in that midfield improve us.
30M is nothing.
Look, the BETTER move would be to keep Gana, sell Morgan, McCarthy, Besic, who would probably fetch 15-20M, lose 2x Gana's Salary, and two young, cheaper midfielders that would make us more versatile like Sangare and Santiago Sosa / Bruno Guimares / Boubakary Soumare or someone like that.
I'm all for selling our aging players, but man, not when we've got literally no one that can replicate what he does.
