Manchester United are now on their longest run without a clean sheet on the road since 1986 after John Fleck opened the scoring for Sheffield United on Sunday.
Fleck bundled home the rebound from close range after John Lundstram’s shot had been saved by David de Gea to put the Blades in front after 19 minutes at Bramall Lane.
It means Ole Gunnar Solskjaer’s side have now failed to keep a clean sheet in any of their last 12 Premier League away games, their worst run in the competition and worst in the top flight since a run of 15 in the 1985-86 campaign 34 years ago.
