Pictures were shared online of the Madrid squad training ahead of the start of the new LaLiga campaign on Saturday.

And it appeared the players were hooked up to breathing apparatus with Bellingham amongst those sporting a mask.

Fans were quick to jump to social media to comment on the strange looking monitoring equipment with many likening the images to Batman villain Bane.

Other fans commented on Bellingham himself with expectations high ahead of his debut season.

One fan wrote: “Big season ahead.”

Whilst another simply added: “MACHINE!!!”

The England International has been the marquee summer signing for Madrid boss Carlo Ancelotti and is slated to make his competitive debut this weekend.

Real travel to Athletic Bilbao to face last season’s eighth place finishers.

Bellingham and Madrid have had a mixed pre-season with wins against Manchester United and AC Milan followed by defeats to Juventus and Barcelona.

They’ll be hoping they can go one better than they did last season after finishing second in La Liga behind bitter rivals Barcelona.
