Arsene Wenger must truly hate the sight of Jose Mourinho.
For all the trophies he's won and victories he's enjoyed at Arsenal, the Frenchman is still to conquer his Portuguese nemesis in competitive action.
That's 12-and-a-half years of frustration against various Mourinho sides - a run which includes seven defeats and six draws.
Sure, Wenger did get one up on the 'Special One' in the Community Shield back at the start of last season but we all know that's a glorified friendly and, in reality, this winless streak is still very much active and no amount of touchline pushing and shoving can change that.
