This stepping stone narrative is really short sighted.
When was the last time we sold a player that was considered indespensible? Shaun Wright Phillips, Distin? Maybe at a push Leroy Sane, but the reality is, we are not a stepping stone club. Dortmund would probably fit nicely into that category. We keep our BEST players - Huge difference
Torres is added to the list of players like, Iheanacho, Eric Garcia, Javi Garcia, and further back there was Nastasic, Stefan Savic Trippier et al, who have all moved on to better their careers because they knew they weren't good enough to play a regular role and the feeling at the club was mutual.
