LONDON – Arsene Wenger’s final match at Old Trafford as Arsenal manager ended in defeat with a stoppage time header from substitute Marouane Fellaini earning the points for second-placed Manchester United.

Paul Pogba drove United into the lead in the 16th minute, pouncing after Alexis Sanchez had headed a Romelu Lukaku cross against the post.

Arsenal, fielding a largely second string side, drew level in the 51st minute when Henrikh Mkhitaryan, signed from United in January, beat David De Gea with a well-placed effort.

United’s Marcus Rashford had the ball in the net in the final minute but the effort was ruled out for offside before Fellaini headed in the stoppage time winner from an Ashley Young cross.

Meanwhile, champions Manchester City equalled the record of number of wins in a Premier League season with a 4-1 victory at West Ham United on Sunday and they are closing in on more milestones.

With the title wrapped up two weeks ago, City’s perfectionist manager Pep Guardiola has been keen to keep his players motivated and prove they are one football’s elite sides.

“I’m happy we will receive the Premier League trophy and (have) the chance to be the best team in history in England, with the most points,” Guardiola said.

From Raheem Sterling’s last-gasp winner at Bournemouth in late August to City’s 0-0 draw at Crystal Palace on New Year’s Eve, they won 18 Premier League games in a row, demolishing the 13-match record set by Chelsea in 2016-17.

After beating West Ham, City are on the verge of another record. With 30 wins, they are level with Chelsea’s number of victories in one campaign which they achieved last season.

City have also now equalled the record set by Chelsea in 2004-05 for away wins in a Premier League season but they are not done yet.

With three games left, City need two goals to set a new record for goals scored in a Premier League campaign, the 103 Chelsea netted in 2009-10.
