I'm not bothered whether we sign him or not but that's not putting 2 + 2 together, it's just an opinion. Players don't get in teams, they move elsewhere to play. Barcelona have a lot of midfielders and won the league last year.
I see you have an aversion for literally everyone you see as having "failed" at their previous club, despite several in that category who have been some of our best signings in recent years. Players don't fit clubs for many reasons. Being 50 years old probably not one of them.
We obviously shouldn't be offering this guy €7m or whatever, let him go to Saudi.
