That's the thing about Rafinha.
He could very well be useful for Valencia but he's a ticking time bomb, you feel he will get a decent stretch of games but end up suffering a lengthy injury.
I have read a joke a few days ago.
A former teammate of Rosicky from Arsenal said:
"If you pass by him, look at him and just say "Hi" or "How is it going", he will drop down and get injured".
Well, it is more or less the same with Rafinha.
He will get injured every season till the end of a career.
I don't think that anyone will pay any money for him.
He can only move for free or on a loan.
I mean, if you were a president of any La Liga club, would you pay 5-10M for him plus 2-3-4M net wages (4-8 gross) for a 3-4 years contract?
That is potentially 20-40M invested in him for 4 years and he is only one longterm injury from ending his career...
