I would say to a far greater end that ourselves and many clubs in this country. Athletico Madrid have produced a side that have won the Europa League, could have won 2 champions league and would have likely won 1 if not 3-4 PL titles in the last 7-8 years. This has been done on the back of selling players at an opportune moment.
Our key difference is I don't believe us to be top of the food tree. I think we are the next rung down.
Athletico are a good example mate, similarly they are operating in a City with a neighbor with a bigger global profile. There are subtle nuances though, i think the pathway to CL may be more straight forward then the PL, while they seem to have gone all out to Keep Griezman recently. But i take on board what you are saying.
Its a tricky one, essentially you have to have recruitment and letting players go at the right time correctly almost all of the time. I think the PL is different again and more competitive. In a way i see Spurs and Mordor, in this decision making fork in the road at the moment as an example. Both are pretty close to title winning teams, yet arguably have hit a glass ceiling were they are struggling to improve what they have. Do they sell Kane or say Salah for huge money to reinvest to try and get to City levels or do they stick with what they have, perennially qualifying for the CL or hoping Pep runs out of road at City. The PL is a tough, tough league. I mention them really because that level of competition should be our aspiration.
Its a tricky one really, the margins between reaping and sowing are very fine.
