CROTCHETY Arsenal fans found something to distract them from FA Cup woe against Liverpool – Mikel Arteta’s trousers.

Viewers wondered if the Gunners’ boss “had “ripped” his slacks where he would least want to as he sat in the dugout during Sunday’s 2-0 home defeat against Liverpool.

Mikel Arteta had bigger things to worry about than his trousers as toothless Arsenal crashed out of the FA Cup to Liverpool

Observers pondered how Arteta’s trousers got damaged down the middle

But it was split decision over what could have caused the grey patch on the crotch area of the Spaniard’s clothing.

One viewer summed up the mystery: “What’s going on with Arteta’s trousers?

And unfortunately many of the responses were no less certain.

“Has Arteta got a split in his trousers,” asked one.

And another observer claimed the pressing matter had left him “crying” with laughter as he pondered: “Has Arteta ripped his trousers?”

Many fans were similarly creased-up with amusement.

But on the pitch Arsenal took their eye off the ball, at least in front of goal.

Poor finishing cost them dear as Liverpool sneaked into the fourth round with a late double.

On minute 80, a free kick from Trent Alexander-Arnold sailed in off the head of Gunners defender Jakub Kiwior.

Five minutes into stoppage time, Luis Diaz marched off to cleanly finish off a counterattack.

One fan responded to the Gunners’ waste of 18 attempts on goal by posting: “I’m actually worried we actually have lost the ability to score.”

And amid pleas for Arsenal to splash out on new strikers, Arteta must wonder how his current bunch failed to trouser at least one of their five efforts on target.
