Nightmare for Man Utd as new £52m signing Leny Yoro spotted on crutches with protective boot to spark serious injury fears after early exit from Arsenal friendly

Yoro swapped Lille for United earlier this month in a £52 million move ($68m) but less than two weeks after signing for the Premier League team, the 18-year-old may face a spell on the sidelines. After being forced off in the first half of Saturday's pre-season loss to Arsenal, the centre-back was filmed getting onto the team bus with the protective boot and crutches at their UCLA training base.

United edged out Real Madrid, among others, to sign the talented defender - who is seen as one of the world's most promising teenagers. The Red Devils had a hefty injury list last season, particularly in defence, and manager Erik ten Hag will be praying Yoro makes a speedy recovery - or else they may need to strengthen in that part of the field again.

After the 2-1 loss to Arsenal, Ten Hag said on Yoro's injury: "It is too short [notice] we have to wait over 24 hours and then we know hopefully more. We were very careful especially with Leny. He did only 50 per cent from the sessions so it was very disappointing that he had to come off but let’s be positive and see what is coming out."

According to BBC Sport, manager Ten Hag will speak to the media about this topic and more ahead of United's pre-season friendly against Liverpool in South Carolina on August 3. Before then, the Red Devils will take on Real Betis on Wednesday in San Diego.
