Not a coward, but unambitious. It's his choice in the end. Half of us would take the money over football 'glory.' It all depends whether football is a job or a passion for the player. In Witsel's case, it's clearly a job.
the funny thing is, he was waiting out on us in the same way we were for him. But seriously it just goes to show what sort of person he is and I for one wasn't ever all that keen on him in the first place and certainly not even remotely pissed we lost out on him, my concern is what now?
