Chelsea maintained their iron grip on top spot in the Premier League with a 2-1 win at Crystal Palace and Sergio Aguero fired a four-goal warning that Manchester City will not relinquish their title without a fight.

Goals from Oscar and Cesc Fabregas made it seven wins from eight games for Chelsea, who overcame the sending-off of Cesar Azpilicueta before halftime to stay five points clear.

Aguero lit up the day's early kickoff, scoring all four goals as Manchester City beat Tottenham Hotspur 4-1 in a match of four penalties and a red card for Spurs defender Fabrizio Fabio.

The Argentine scored twice from the spot and had another penalty saved.

City made it 15 goals against Spurs in their last three meeting thanks to Aguero, who scored twice in each half to take his league tally this season to nine goals in eight games. He also had a first-half penalty saved.

Pride of place, however, went to Southampton who thrashed Sunderland 8-0 to stay in third place.

West Ham United moved into the top four after a 3-1 victory at struggling Burnley.

Arsenal's mediocre start to the season continued as they were held to their fifth draw in eight matches, Danny Welbeck scoring late to salvage a 2-2 home draw with Hull City.

Everton returned to form with a 3-0 win over Aston Villa.
