Como is like other small clubs with many difficulties from finance to player resources. With those clubs, each summer transfer season is a very big challenge for them, as they have to let many players go like in loan expirations, sales to bigger clubs, and rebalance their club finance. These things make many wild changes in their player resources and success in the past season is not a foundation for their success next season when some clubs have 80% new players in a next season for example.
Como has been playing well in this season but they will face with uncertain and chaotic summer that can help them to improve their squad or witness its quality decline. We only can know how it goes after a next season passes several months and Como perform with their new squad.
Como is doing fine at the moment, better than expected at least, but that doesn't mean we are seeing Cesc Fabregas at a "bigger" club that quickly. Just because he had one semi-decent team doesn't mean that he is going to be at a big level already. He had one season at this level, so he needs a bit more experience before he leaves for a better team.
What happened to Vincent Kompany changed everyone's perspective, everyone saw him manage one bad English team to relegation and move to Bayern Munich, so now whenever a new manager does decent with a bad team, they assume a big club will get that manager. What happened to Vincent Kompany was not normal, in normal cases we do not end up with these kind of moves.
