Pretty sure Merse was still around under Wenger, yeah. Always had the impression his alcohol and gambling issues sort of washed him out of the squad as the Wenger wellness regime appeared.
I had not understood the stat correctly, thought the commentary had made a mistake when they said 86, but I see how they meant it now.
Not to hate on Xhaka gratuitously but it's another reason to look forward to him and one or two others departing.
