Arsenal and Manchester United were both unable to find a way through as the latter lost ground on Premier League leaders Manchester City.
Nicolas Pepe was the hosts’ biggest threat, twice going close, while Edinson Cavani will know he should have scored at least once after two big misses.
The stalemate ensures United lose further ground and leaves City sitting three points clear at the top with a game in hand, while Arsenal have leapfrogged Chelsea into eighth.
It’s been a bad week for Manchester United, while Arsenal continue to improve under Mikel Arteta.
