With an aggregate lead of 16-4 over their last five matches, the verdict is clear: Oliver Glasner is coaching’s equivalent of kryptonite for Unai Emery.
This was Glasner’s fourth win in five matches against the Aston Villa boss and his third this season alone, after Crystal Palace also beat Villa 4-1 at Selhurst Park and won 2-1 at Villa Park in the Carabao Cup.
Throw in the Eagles’ 5-0 triumph at Selhurst Park in the final game of last season — by which time, admittedly, Villa had already secured a top-four finish — and Palace’s superiority in these matches has reached an embarrassing level for Emery.
