Eddie Nketiah's 90th-minute winner gave Arsenal a thrilling 3-2 victory over Manchester United to restore a five-point gap to Manchester City at the Premier League summit.
Arsenal kicked off just two points clear at the top, having seen City win twice since they last played, but they reestablished a more comfortable cushion at the end of a gripping Emirates Stadium encounter on Sunday.
United – themselves maintaining remote title hopes – scored first through Marcus Rashford, only to require a scruffy second-half leveller from Lisandro Martinez after goals from Nketiah and Bukayo Saka had turned the game on its head.
Only Arsenal looked capable of providing a further twist, though, and it came through Nketiah with seconds remaining of normal time, giving the Gunners surely their biggest win of the season so far.
