Following a fiery match at the Bridge, you only have to look at the Premier League table for some fans to be more worried than others. So who were last night's big winners and losers?
After what seemed like an eternity to get back on track, Chelsea really did look something special. David Luiz was the difference. He made crucial tackles, an even more important goal, and possibly avoided a sending-off. The only real blot on the evening: Torres still couldn't break his duck, though he has been steadily improving.
The win for Chelsea sees them back into the top four. With a game in hand, they look to cement their place in the Champions League for next season. If they continue like this, expect whispers of silverware down at Stamford Bridge.
Beating Sunderland at home is the only thing keeping Arsenal from closing the gap to a single point, though injuries to Fabregas, Walcott, Van Persie and Vermaelen are going to make those three points a little harder to get.
Sunderland will be hoping that the same team—or, even better, one without Van Persie and Fabregas, and will make the tie sound more open than it did a week ago.
That said, the title is up for grabs. Arsenal will need to be on their best if they really want to challenge.
While getting the fifth spot might look out of reach, Liverpool can at least close the gap on Spurs and make it interesting. Eight points and a game behind, they will need a miracle, if they want to play Champion's League football next season, though they could still get through courtesy of the Europa League.
But what better boost than to welcome a newly defeated United side, who will likely miss Vidic and possibly Evra at Anfield? While their form has dipped a little in recent matches, they will look to get all three points and will have a massive say as to who will be top at the end of the season.
While not completely out contention for the league title, Man City still needs some more miracles before the end of the season. Chelsea winning has suddenly put Man City under a lot of pressure.
By Monday night they might be hovering over Spurs at fourth place due to virtue of goal difference, putting themselves in danger of losing the Champions League dream for another season. The self appointed pretenders to the throne could be up against Europe's second best.
A casualty of Chelsea's re-entry to the top four, Tottenham now has to worry about avoiding the fifth spot and going back to the Europa League.
They have a game in hand over Man City but have an inferior goal difference. What looked like a straight duel with Man City has become a three-way fight for two spots. After a great debut season in the Champions League, as well as the extra income and exposure, they will be determined to avoid fifth.
But with this season's run in the Champions League far from over, they need to get their priorities right.
Man United really have it all to do.
The week could potentially be worse if they can't avoid defeat at Anfield. Evra picked up a late knock and could miss the tie, but, more importantly, Vidic was sent off and will leave Fergie without his two first-choice centre backs.
With the gap still at four points they will be boosted if Arsenal cannot beat Sunderland.
The league is still theirs to lose, but they will need to be at their best. Arguably, Luiz should've seen red, but there's nothing that can be done now. They can only look forward and get results.
A potential loss and Arsenal win will mean that Arsenal will stay a point behind and a game in hand, which will be advantage Arsenal until they drop points. A superior goal difference may be more important than expected come the end of the season.
