Fans in hysterics as lone AZ Alkmaar fan spotted in West Ham away end wearing fierce rivals’ shirt

THE shirt hit the fan when TV viewers spotted a lone supporter roaring on AZ Alkmaar in the away end at West Ham - donning a Millwall top.

He was hailed online for "decent sh*thousery" but many wondered if he took the shirt of the Hammers' fierce rivals off once he left the ground.

He was seen leaping with joy in the visiting hordes when Alkmaar nicked a shock lead in the Europa Conference League semi-final first-leg.

But some fans felt it was "karma" when the Hammers revived to win 2-1.

One viewer said: "Fair play to him, but I bet he covers it up outside."

Another noted how London Stadium is less compact than West Ham's old Upton Park venue.

He wrote: "Safe as houses in that soulless hole of a ground now they’ve sold out. Good lad."

And a few fans even pondered if the supporter was not an AZ supporter, but genuinely a follower of the Lions from South London.

One posted: "Or just a Millwall fan in the Alkmaar end, either way, decent sh*thousery, love it."

The Hammers' hopes of a first major trophy since 1980 were rocked when Alphonse Areola fumbled in Tijjani Reijnders' low shot on 41 minutes.

But ex-Brighton star Mat Ryan turned the tide with a completely different type of goalkeeping howler.

The Australia captain recklessly punched Jarrod Bowen in the face when challenging in the air - as the England winger headed over.

Said Benrahma's resulting penalty levelled it, before Michail Antonio pounced on a rebound for the West Ham winner.

One fan responded by referring back to the wrong-shirted Alkmaar follower with this jibe: "He ain't dancing now."
