Marquinhos problem is just how good the Silva-Luiz partnership has been working.
You can't bench Silva since he's so vital to the team and still performing well at a high level. and Luiz? cost PSG a lot of money and he has played well with Silva and I doubt he wants to sit on the bench. that leaves Marquinhos in tough Position.
I said it before he should've thought this through better and instead of just chasing the cash and now he's paying for it by riding the bench. If he truly wants to move he needs to Prove it and instead of using us for leverage for more playing time other wise it's a waste of time.
