The 22-year-old singer, who is on the UK leg of his tour, was recently given a private tour of the Gunners’ facilities in Bell Lane.

Midfielder Alex Oxlade-Chamberlain posted on Instagram: “Really enjoyed the show on Wednesday and great to take Justin around the training ground last night.”

His comment prompted one fan to ask: “Is Bieber really a gooner? Is this confirmed?”

But another one posted: “Please say Wenger made you do it.”

Fellow Gunner Mesut Ozil also posted a photo, on Facebook, showing him swapping shirts with the pop star.

Ozil commented: “Nice to see you Justin Bieber.”

He had a mixed response, however, with one man asking: “Why you [sic] wasting a perfectly good shirt on that bellend?”

One warned: “My god, arsenal fans are gonna get soooo trolled for this, why mesut oh why [sic]”

Another person had a more dire warning: “So many of the arsenal fans will become either Chelsea/Tottenham fans.”
