Manchester United dropped their first Premier League points of the season on Saturday after Peter Crouch's first goal for Stoke secured a 1-1 draw at the Britannia Stadium.
United had looked on course to maintain their 100 percent start to the season -- and a two-point lead at the top of the table -- after Portuguese winger Nani fired them ahead on 27 minutes.
But former Tottenham striker Crouch soared high to head home a corner on 52 minutes as battling City deservedly secured their first ever Premier League point against Manchester United.
The result left United top of the table on goal difference from arch-rivals Manchester City, with both clubs on 16 points after six games.
"I was pleased with the performance from the lads - they battled really hard and played like real champions," United manager Sir Alex Fergsuon told MUTV.
"A draw is probably a fair result. It's a difficult place to come to."
Torres, who was widely ridiculed after his open goal miss at Old Trafford, looked to have banished the blues after rifling home a superb opener to put Andre Villas-Boas's side ahead at Stamford Bridge.
The £50 million striker had a hand in Chelsea's second goal scored by Ramires on 36 minutes but then saw a promising display take a disastrous turn when he was given a straight red for a two-footed lunge on Swans midfielder Mark Gower.
The dismissal did not prevent Chelsea clinching the win however, Ramires adding his second before Ashley Williams grabbed a late consolation for the promoted Welsh side. Didier Drogba added a fourth in the dying moments.
The win leaves Chelsea three points behind leaders Manchester United and second-placed City.
Dutch striker van Persie scored in the 46th and 71st minutes before Alex Song added a third late on.
The win relieved the pressure on Arsenal manager Arsene Wenger but left Bolton rooted to the bottom of the table with only three points.
Ba added his second only three minutes later, heading home to leave Blackburn reeling. Rovers fought back with a David Hoilett goal on 37 minutes but Ba sealed his hat-trick early in the second half to make sure of the points.
