Manchester United set a new club record in their 0-0 draw with Arsenal but lost ground on Manchester City in the title race
Ole Gunnar Solskajer’s side lost to the Blades at Old Trafford during the week but their away form has been much more impressive.
The stalemate at the Emirates Stadium made it 18 Premier League games without defeat to set a new club record.
The Gunners went closest when Alexandre Lacazette’s clipped free-kick hit the bar after the break while United keeper David de Gea saved well from Emile Smith Rowe and Nicolas Pepe also threatened to break the deadlock.
De Gea’s counterpart Bernd Leno also distinguished himself with an athletic fingertip save from Fred in the first half.
Manchester United came within inches of winning it in the closing stages when Cavani saw a close-range effort deflected wide off Leno and the Uruguay striker then hooked a superb cross from Aaron Wan-Bissaka just wide when he looked certain to score.
Arsenal gave a late debut to Martin Odegaard, signed on loan from Real Madrid, but he had little impact and the stalemate leaves United three points behind Manchester City having played a game more.
Both teams are back in Premier League action on Tuesday as Arsenal travel to face Wolves, while Manchester United host Southampton at Old Trafford.
