Lewis-Skelly jokes at Rudiger after STAMP in Arsenal’s UCL win over Real Madrid.

Myles Lewis-Skelly took to social media to poke fun at Antonio Rudiger after Arsenal's Champions League win over Real Madrid on Wednesday.

Mikel Arteta's side cruised to a 5-1 thrashing on aggregate against Los Blancos, having built a commanding lead following their 3-0 win in the first leg of their quarter-final clash at the Emirates last week.

During the game, Rudiger was involved in a foot race with Lewis-Skelly, which ended in the Madrid defender appearing to stamp on the teenage star's torso as he was grounded.

Not even an hour after full-time, Lewis-Skelly shared a collage of photos from Wednesday on Instagram, two of which appeared to take aim at his opponent.

The third photo was a screenshot which showed Rudiger's foot planted on Lewis-Skelly's stomach, while the following image was of the teenager laughing at his phone before the game.

Rudiger escaped any form of punishment for his stamp, while Lewis-Skelly was not significantly harmed by the incident.

Arsenal fans took to social media to react to the controversy, with one labelling it 'cowardly' and others expressing their disbelief over the fact Rudiger went unsanctioned.

One fan wrote: 'How is this not red??? What the hell is the VAR even for???'

Another commented: 'Rudiger's stamp on Lewis-Skelly is as cowardly as it gets. Surprised the referee and VAR looked away.'

A third said: 'How Rudiger didn't get a card for his stamp on MLS is beyond me.'

After PSG edged by Aston Villa on Tuesday, Arsenal will face the French champions in the semi-finals, with the first leg set to be played two weeks from now on April 29.

Meanwhile, on the other end of the Champions League bracket, Barcelona will face Inter Milan in the final four, after sweeping Borussia Dortmund aside to win 5-3 on aggregate on Tuesday.

Inter had similar success against their respective German giants, having knocked out Bayern Munich 4-3 after two legs following a 2-2 draw on Wednesday.
