Arsenal extended their unbeaten Premier League run to seven matches in an exciting, but goalless, draw against Manchester United.
In an open contest at Emirates Stadium, Fred saw his 19th-minute shot denied by the fingertips of Bernd Leno at full stretch, before Bruno Fernandes curled narrowly wide as United enjoyed the better of the first-half chances.
Arsenal started the second half brightly, with substitute Willian and Nicolas Pepe both having shots blocked in quick succession.
Alexandre Lacazette powered a free-kick against the bar and Emile Smith Rowe forced David De Gea into a smart save with the follow-up.
Those opportunities came either side of Edinson Cavani spurning two good chances for United.
For the first, the Uruguayan sidefooted just wide with Leno stranded, while the second was a last-minute spectacular volley that went the wrong side of a post.
United's club-record 18th away league match unbeaten keeps them second, but they drop three points behind Manchester City.
Arsenal are ninth with 31 points.
