Relegation-threatened Everton earned a priceless win against misfiring Manchester United on Saturday as Chelsea hammered Southampton 6-0 on a potentially decisive day in the race for the Premier League top four.
Arsenal stumbled again, losing 2-1 against Brighton while Leeds pulled further away from the drop zone with an emphatic 3-0 win against struggling Watford. Arsenal are having a wobble at the wrong time after putting themselves in a strong position to qualify to play in the Champions League for the first time since 2016/17.
The home defeat against Brighton means Mikel Arteta's men have now lost three of their past four league games and they are now level with fierce rivals Tottenham, having played the same number of games.
Brighton took the lead at the Emirates Stadium when Leandro Trossard turned home a low cross from Enock Mwepu while the Zambian midfielder himself added a second. Martin Odegaard scored a late consolation.
Raphinha, Rodrigo and Jack Harrison all found the net to give Leeds a third win in four matches and take them nine points clear of the relegation zone.
Manchester City and Liverpool go head to head at the Etihad on Sunday in a top-of-the-table clash that could decide the outcome of the Premier League.
