Thought the same thing.
Even if he was eligible, Pep would probably say there's no point in him missing the Saints game to sit on the bench vs. Monchengladbach.
I do think we're reaching a stage where he simply has to be given a reward for this form now though. 13 goals and 3 assists in his last 6 games...you can't ignore that or you piss people off and disincentivise them.
