Arsenal fans took to Twitter to lay in to Shkodran Mustafi following their 1-1 Champions League draw to Paris Saint-Germain.

Mustafi, 24, joined Arsenal this summer for £35million and made his European debut for the Gunners against PSG on Tuesday night.

But the former Valencia centre-back was caught napping as Edinson Cavani stole in to open the scoring with a header just 42 seconds into the game.

Arsenal fought back with a late goal through Alexis Sanchez but the damage had been done.

Supporters took to social media to share their disappointment with their new man with some fans even saying he was defending like a schoolboy.

Here are some of the best messages posted to Twitter in response to Mustafi’s performance:

The central-defender was one of three senior additions to the Arsenal squad this summer.

Mustafi has been joined by Granit Xhaka and Lucas Perez in the north Londoners team, but the new-look Arsenal side were powerless to prevent P.S.G taking a valuable point from the fixture.

Arsene Wenger will now return his thoughts to domestic football after the draw.

His side take on Hull City in the Premier League this weekend and will be looking to make it 10 points from their first five fixtures this term.

Wengers side have lost one, draw one and won two of their four domestic encounters so far.
