Then why don't we get rid of Xavi who is 34, earning tons of money, and had a way worse season than Yaya?
Everyone at Barcelona is going to have high wages. It's a PROFESSIONAL football club and one of the most prestigious in the world. At first you guys were all agreeing that we need a physical presence in midfield but now that there's rumors of a Yaya return; you're all worried about money that you don't pay. If we get rid of Song then that's a chunk of Yaya's wages, anyway.
Yayas wages will be on top of his transfer fee.
Signing a 31 year old for a big fee and then giving him huge wages will never happen.
If he was available for free it might be different, even then though would it be right to take him in and give him more than Iniesta for example.
Xavi has declined clearly but his wages are justified for what he has done for the club and as a symbol for the other players to look at how the players can be rewarded for a career dedicated to Barcelona.
People here will complain about Xavis performances but his wages are never in doubt as he has earned them over the past 17/18 years.
