Relentless Southampton beat Leicester City 2-0 at home and there was also a tight 1-0 victory for Manchester United over Crystal Palace although champions Manchester City were held to a 2-2 draw at lowly Queens Park Rangers in the evening kickoff.
What Mourinho really wants is for Chelsea to be crowned champions in May but for the moment he is settling for his self-appointed award after Chelsea’s come-from-behind win thanks to goals from Gary Cahill and Diego Costa.
“I think we have a very good chance to win the title but I think we, Arsenal, Manchester City, Manchester United and Southampton are all still in the race. All we can say is that we are the champions of the autumn,” he said.
“I think we were very impressive, we want to play, we want to win, we want the ball. The best team by far was the blue team and the team that deserved to win was Chelsea.”
Although he does not think Chelsea can emulate Arsenal’s achievement of 2003-04 by remaining unbeaten for the whole season, he was delighted after his team took the three points back to west London.
“Unbeaten through the season is the impossible job, I think we will lose eventually,” he said.
Chelsea moved on to 29 points from their opening unbeaten 11 games, four ahead of Southampton who made it 11 wins out of 12 in all competitions after Shane Long came on as a 67th-minute substitute and scored with a left-foot shot on 75 minutes and a right-foot effort five minutes later.
Champions Manchester City’s poor run continued when they twice came from behind at QPR to draw 2-2 thanks to two goals from Sergio Aguero who took his league tally to 12 for the season.
Charlie Austin had two efforts disallowed early on before putting QPR ahead in the 21st minute. Aguero made it 1-1 11 minutes later before QPR went back in front after 76 minutes when Martin Demichelis headed into his own net.
Aguero saved City’s blushes with a well worked equaliser seven minutes from the end but City have now only won once in their last six matches in all competitions.
The result meant City dropped two more points behind leaders Chelsea on 21 points, while QPR stayed 19th with eight points.
Elsewhere, goals were in short supply as Manchester United ended a three-match run without a win by beating Crystal Palace 1-0 at Old Trafford with a 67th-minute effort from substitute Juan Mata.
The goal was somewhat fortuitous as Palace goalkeeper Julian Speroni, who had an otherwise sound game, allowed Mata’s long-range shot to slip through his hands.
Mata, who had only been on for four minutes before breaking the deadlock, told Sky Sports United needed the win.
“It was massive. It was very, very important after three games without winning. We needed the three points and finally we got them. It was a difficult game, they played very well in the first half, were very compact and had a great chance to take the lead.”
Burnley also scored a narrow 1-0 win at home, with a header from Ashley Barnes after 50 minutes at Turf Moor enough to give them the three points against Hull City and their first league win since being promoted back to the Premier League at the end of last season.
They remained bottom on seven points but at least closed the gap on QPR and Leicester, the other two promoted teams also in the drop zone. Since beating Manchester United 5-3 on Sept.21 Leicester have taken only one point from their subsequent six matches.
The most exciting match of the afternoon came in the lunchtime kickoff at Anfield where Emre Can scored his first goal for Liverpool with a long-range shot after nine minutes which took a deflection off Cahill’s shoulder and left Chelsea keeper Thibaut Courtois stranded.
Cahill pulled Chelsea level after 14 minutes — awarded after the Goal Decision System proved the ball had crossed the line even though the defender’s shot was smothered by Liverpool keeper Simon Mignolet.
Costa settled the points in the 67th minute when he put Chelsea ahead with a low, powerful drive, but Liverpool thought they should have had a penalty in the 88th minute when Cahill appeared to handle a Steven Gerrard shot.
Their strong claims were denied, though, as they had to contemplate a third defeat in a week.
In the other game West Ham United, who are fourth, drew 0-0 at Upton Park with Aston Villa who ended a run of six straight defeats.
On Sunday, as well as the Swansea-Arsenal match, Sunderland are at home to Everton, Tottenham Hotspur are at home to Stoke City and West Bromwich Albion play Newcastle United.
