Arsenal fans have rinsed Ainsley Maitland-Niles after his cameo appearance against West Brom on Saturday night.

The England international came off the bench to replace Hector Bellerin in the 4-0 win at the Hawthorns.

But supporters quickly noticed something different about his kit.

The right-back appears to be wearing a pair of long johns as well as an undershirt.

The weather was freezing on Saturday night in West Bromwich, with snow hurtling down throughout much of the evening.

It even threatened to see the game called off but the match went ahead, much to the home side's regret not long after the first whistle.

Arsenal completely dominated the match, winning 4-0 thanks to goals from Kieran Tierney, Bukayo Saka and a brace from Alexandre Lacazette.

It is the third win in a row for the Gunners and moves them up to 12th, six points off the top four.

For Mikel Arteta it is a remarkable turnaround from a point where relegation loomed over them, but victories over Chelsea, Brighton and now West Brom has boosted their confidence.

And fans are starting to enjoy Arsenal once again, even poking a bit of fun at Maitland-Niles, whose odd kit arrangement had some mistaking him for Father Christmas.

One supporter said: "From the waist down he looks like he's wearing Santa claus costume."

And another tweeted: "When you have to beat WBA at 9 and give presents at 12."

While this fan replied: "Looks like he’s forgot his pe kit n had to go lost property and grab what he can."

Ainsley Maitland-Niles got a bit of jovial stick for his Arsenal outfit

A fourth said: "Grandad called.. He wants his long johns back!"

"Santa outfit," another quipped.

This fan said: "Making good use of one's xmas stockings."

Arteta will not mind, though, and commended his players after making it through the festive period with nine points out of nine.

He said: "We had a big week, three games in seven days, and we managed to win them and everything looks much better.

"It was difficult conditions but the team looked sharp from the start. It's a big win.

"After the results we had before we had to lift things straight away. Now we have got some discipline back. We look more creative in the final third and we look solid at the back."
