Sixth-placed Manchester United fell behind at home to Middlesbrough before goals from Anthony Martial and Paul Pogba in the last five minutes brought about a 2-1 win.

It was Middlesbrough’s first attempt on target.
Zlatan Ibrahimovic, with 11 goals in his previous 10 games, was annoyed to have a 12th ruled out in the first half, for a high foot.
Martial, who had earlier hit a post for United, brought them level with only five minutes to play and a minute later Pogba earned United their fifth successive league win.
West Bromwich Albion moved above Southampton into eighth place by coming from behind to beat them 2-1 at St Mary’s.

Swansea City, who sacked manager Bob Bradley earlier this week, slumped to a 3-0 home defeat by Bournemouth to leave them bottom of the table at the halfway stage of the season.
Benik Afobe, Ryan Fraser and Josh King were the scorers as Bournemouth moved back into the top half of the table.
Sunderland stayed in the relegation places with a heavy 4-1 defeat at Burnley, whose impressive home form continues to make up for having taken only one point all season on their travels.
