This is how they stand at the top of the Premier League. Chelsea are now seven points above Arsenal.

QPR boss Chris Ramsey: "I am very, very disappointed to lose. Detail kills you and when you have top players like they do, you get done. One shot or two shots and the top players score.

"We have let two or three goals in from the same position the last few weeks and players haven't been able to concentrate enough.

"We are still in with a fight, everyone is disappointed and I just feel sorry for the crowd. We have ourselves to blame because of our concentration. Our concentration has been appalling. We have let late goals in in most games. The players don't need lifting, they will lift themselves."

This is the moment Branislav Ivanovic was hit by an object thrown from the crowd.

Saintlammy: Chelsea rugged when it is necessary, champions don't always outshine opponents but they do get the desired result.

Chris Lloyd: Margins in this title race so much finer than they appear, Chelsea fell lucky and late on the right side of them today.

"Real Madrid and Barcelona do not play sides in the bottom three and have such tough games, and that's what makes the Premier League so great.

"You have to compete. Chelsea have big physical players. You have to match the desire and that's why they are going to become the champions. We just focus on us. We have a number of games and feel our destiny is in our hands, if we play like that we will be fine."

QPR midfielder Joey Barton said: "We're devastated. We definitely deserved at least a point. We are massive underdogs and you have to be switched on for 90 minutes. Greeny (goalkeeper Robert Green) is gutted but he has probably saved us 10 or 12 points this season. If we play like that for the rest of the games we should be safe. We're gutted. The lads have put in everything in there. You could see what it meant to Chelsea to win that game.

"Nobody expected us to get anything. We kept the belief in the camp. After four points on the road people started believing in us. Leicester were dead and buried if you listen to the media but now it looks as it will be two teams from five. We are game for the fight and we will have to scrap until May, but we knew that in August."

More from Chelsea manager Jose Mourinho: "To keep a good balance emotionally was very important. This was a final for both teams and both teams managed to compete at a very high level but at a clean way without losing control of emotions. The referee helped keep control.

"Didier (Drogba) was amazing. Ninety minutes is too much for someone not playing a lot and it's difficult for a player to have 90 minutes in his legs but he had 90 minutes in his brain.

"He is a fantastic example for us when we needed a big personality to step up. As John (Terry) did, very safe, very calm and controlled.

"It is one step closer. We need three wins and two draws. When we have one match more to play than the other teams. Our situation is good. Pure mathematics. We need 11 points."

Chelsea manager Jose Mourinho: "Our situation was positive. One point would be one less point we need but the reality is three points and it is one less match we need to win.

"It is an important step. The best quality was we controlled the game very well. QPR can score, have dangerous players and are very direct. We kept calm and tried to keep calm against a side who were very well organised defensively.

"During the season you always have these moments where you lose and win points at end of the game. We lost points at the end at Old Trafford and won points in last few minutes today.

"I always thought it was very important to keep a clean sheet because it was always going to be difficult to keep a clean sheet here."

Seeing the footage back, there are a number of objects thrown at the celebrating Chelsea players immediately after Cesc Fabregas's late winning goal. A plastic bottle ends up on the pitch, as do a number of coins.

Branislav Ivanovic holds the back of his neck, indicating that he has been hit by a coin, while Nemanja Matic may have also been hit by an object as well.

Chelsea striker Didier Drogba says: "I'm very happy with the way we played. I was trying to give my best, always for the team and I'm really happy. We have been top of the league from the beginning of the season."

Chelsea goalscorer Cesc Fabregas says: "It was very difficult to play. The pitch was very dry, it was windy and not the circumstances we want to play football. But even in the difficult moments we played well. Didier held up the ball well."

Former Charlton midfielder Paul Mortimer: "It was a good performance by QPR and it came down to a fine margin. They gave it everything. The way Chelsea's players celebrated at the end shows what it means to them."

We are hearing unconfirmed reports that Branislav Ivanovic may have been hit by an object thrown from the QPR supporters following Cesc Fabregas's late goal. More on that when we have it.

Captain John Terry runs, jumps in the air, fists pumping, screaming in joy. What a big three points this is - and he knows it. They were nowhere near their best, but no-one from Chelsea will care about that.

They only had one shot on target in the whole game. And that came in the 88th minute. But the ball ended up in the back of the net from Cesc Fabregas's shot.

David Broome: Why do opposition keepers keep giving chelsea late winners? I've never seen keeper mistakes like last two to give Chelsea wins.

Diag O'Nally: See the reason why Rob Green is not a good 'keeper? Not good enough for England.

Kwasi Boafo: That's what champions are made of. Play bad but get the goals in. Chelsea spot on for the title.

"We're going to win the league," chant the Chelsea fans. They are heading seven points clear. If this stays the same, that is.

Cesc Fabregas may well be the match-winner. He ends the game on the bench with defender Kurt Zouma brought on to tighten things up.

BBC Radio London

Former Charlton midfielder Paul Mortimer: "It was always going to be a bit of brilliance or a mistake to change this game. And it was a poor kick from Rob Green which has proved costly.

"Eden Hazard did well to drift out wide and give it to Cesc Fabregas who finished well. You can blame Green for the kick, but for me QPR's defence did not react quick enough."

This is what champions do. Cesc Fabregas arrives late in the box after a well-worked move down the left wing involving Eden Hazard and Oscar. Fabregas sidefoots the ball home from 16 yards out and Chelsea lead. Heartbreak for QPR. Manager Chris Ramsey has his head in his hands.

It came from a poor clearance from QPR goalkeeper Robert Green.

Chelsea. One shot on target. One goal.
