Marseille No2 Passi: No decision yet on QPR's Barton
Barton has been benched for the past four games.
"He was good when he played. Now he plays less, but the bottom line is that when he comes on the field, he continues to show he is still the same.
"I think the renewal of the contract must be in relation to everything that is Joey Barton, not only when he plays," said Passi.
