London: Chelsea kept their faint Premier League title hopes alive with a 1-0 win over Southampton, while Mesut Ozil's stunning strike fired Arsenal to a 1-0 victory against Newcastle United on Saturday.
With runaway leaders Manchester City in action against Tottenham Hotspur later on Saturday, the focus turned to the clubs desperately trying to hang onto their coat-tails.
At Stamford Bridge, Chelsea sealed their second successive win to move within 11 points of City and draw level on points with second-placed Manchester United, who face West Bromwich Albion on Sunday.
After a tame opening from the champions, who started with star striker Alvaro Morata on the bench following a back injury, Antonio Conte's side finally opened the scoring in first-half stoppage-time.
Marcos Alonso provided the breakthrough, the Spanish wing-back curling a free-kick past flat-footed Southampton goalkeeper Fraser Forster from 35 yards.

Heavily linked with a move to Manchester United when his contract expires at the end of the season, Ozil showcased his talents for any interested clubs when he put Arsenal ahead in the 23rd minute.
After an Alexis Sanchez shot deflected into Ozil's path, the German midfielder smashed a superb volley past Newcastle goalkeeper Rob Elliot from the edge of the area for his third goal of the season.
Newcastle's eighth defeat in their last nine league games leaves Rafael Benitez's side mired in relegation trouble.
Brighton and Hove Albion's Glenn Murray missed a penalty in his team's 0-0 draw against high-flying Burnley at the Amex Stadium.

Congolese striker Kachunga was stretchered off soon after, but the Terriers doubled their lead through Aaron Mooy's close-range finish in the 23rd minute.
A bad afternoon for Watford got even worse when Troy Deeney was sent off by referee Michael Oliver for a lunge on Collin Quaner in the 33rd minute, making it three red cards in their last three games.
Laurent Depoitre bagged Huddersfield's third in the 50th minute before the visitors had Jonathan Hogg sent off for a second booking.

Christian Benteke put his penalty misery behind him to inspire Crystal Palace to their first away win of the season as 10-man Leicester City were beaten 3-0 at the King Power Stadium.

After the Belgian striker's 19th-minute opener, he set up Wilfred Zaha for a 40th-minute goal, with Bakary Sako adding the third in the final moments as Palace moved up to 14th place.
