It was not a perfect ball in to chadli but it was a ball that chadli received and passed on to the goal scorer
What if that incredible defensive clearance he made for Besiktas last week had landed at the feet of Kaboul on the halfway line who then lashed it into the net - would you count that as an assist?
What if in yet another of his strolling back onside episodes he gets flagged and the opposition keeper smacks the resulting free kick off of a defender into his own net - does he get credit for that?
