Why is everyone ignoring the most important point here. Money in modern football is becoming fast irrelevant. We are not a club that needs to sell. I doubt anyone here is owner of the club to care so much about how much was spent on a player. Why does everything have to revolve over money.
A club like us only should get rid of players if they are:
1) deadwood - they just play so bad (aka Adriano in last season) or are not played for other reasons (Vidal) or are simply past their prime (like Mathieu is becoming) and become a liability in games.
2) want to leave themselves - it is not a good idea to keep unhappy players on roster for various reasons.
We are among top 3 richest clubs in the world, yet fans are obsessed with "if good offer comes we should sell", like it is their own personal money involved. What a fan should care and only care is success on the field. For success on the field, as many quality players we can hold without it becoming an issue, the better it is. Arda, no matter if he is "worth the pricetag", would be most probably a starter in 99% of other clubs in the world. Having such a great player, willing to also bench in squad and being happy, is a luxury, no quality players want to bench. Notice how rare it is that top quality players are willing to share a starting point with someone else. We had that luxury with goalkeepers last season, look how long that lasted.
So he is "only" a squad player and excellent in Neymar role. Who the fck is saying Neymar will not get injured in spring. But oh i can see how 50 million in cash is happily going to run around in the field doing as good as Turan has done this season.
Also the goddamn mistake in El Classico. Yes lets sell because a player made a mistake in a game rofl. Hey, did he score an own goal? No. Did he cause a penalty? No. Did he let someone go pass him 1v1 with goalkeeper and score? No Did he give a backpass to allow opponent to score? No
Those are the mistakes u can really blame a player individually, for rest it will always be a team-fckup.
