The time has come to wrap this. Diego Costa's Chelsea career is up and running. So too Jose Mourinho's season. The new-look, big-spending Blues mean business. For Burnley, they need to learn fast if they are to survive. We're back on Tuesday as Arsenal take their first steps on the Champions League road they hope will lead all the way to Berlin on 6 June 2015. Until then.

So, what next for Burnley? Well, it's a testing game at Swansea, fresh from a surprise 2-1 win at Manchester United, on Saturday before a home match against. . .Manchester United. As Sean Dyche rightly points out, there are no easy games at this level. Not one.

Burnley boss Sean Dyche speaking on Sky Sports: "It's the reality of the market that we are going into, and Chelsea are at the top of that. They have power, quality, pace and can hurt you in many ways.

"That's what you get for £300m or whatever. We kept trying to play and will try to keep the inner quality, and inner belief.

"We will learn from a game against Chelsea, it's the top of the market and they will be a force this season."

More from Chelsea boss Jose Mourinho: "We've explained to Diego Costa what people like in the Premier League, what we don't like, and the kid presented himself here with a fantastic and polite attitude and he was booked. The kid wasn't happy and I hope he doesn't get any more unfair decisions.

"No, Thibaut Courtois isn't my first choice for the rest of the season. He was my first choice today. The rest of the season? Who knows?

Burnley boss Sean Dyche speaking to BBC Sport: "The players will learn from the game about the enormity, the occasion of Premier League games. The players will learn from a match against a team like Chelsea. We are all learning from that, the group will learn from that.

"We have to keep going, and we did in the second half. We continued to press and tried to break them down. That's against a team who are at the top end of the business. We have to be realistic, not defeatist.

"Our journey is slightly different from Chelsea's. It's not about trying to get that game out the way. We enjoyed it, but we don't enjoy losing."

Referee Michael Oliver showed he is lacking experience by booking Chelsea's Diego Costa against Burnley, claims former Premier League match official Graham Poll.

Replays showed that Costa had been fouled and Chelsea should have been awarded a penalty.

"Michael Oliver is an excellent referee but still inexperienced at the very top level dealing with world-class players," Poll tells the Daily Mail., external "He met one at Turf Moor in Diego Costa."

Jose Mourinho speaking to the BBC's Juliette Ferrington: "We should have had a penalty and it wasn't unlucky it was unfair, it wasn't simulation but a clear penalty.

"Petr Cech was disappointed but football is sometimes like this, players can often be unhappy and be unhappy with managers. But between the group of players and their mates they have to be supportive.

"I hope he doesn't want to go and I hope he doesn't have offers to go and if he does have offers he refuses to go. I would be delighted to have two of the best goalkeepers in the world in my squad."

Jose Mourinho speaking to Sky Sports: "When you come to a place like here and you are a goal down against a difficult team and in a difficult place then players can get down heartened and lose faith. Burnley are a direct and physical side but overall we had good control and we showed moments of class.

"At half-time I told the players 4-1 kills the game but 3-2 makes it dangerous. I agree completely with Cesc as man of the match. He controlled the tempo of the game and was responsible for the best phase of our play. Diego was very important as he made our first goal and that was very important."

Jon in Bristol: After a game like this, Burnley must reflect and ask themselves "Did we do ourselves proud? Did we try hard enough?" If they can answer those questions positively then they can consider the game a success. This Chelsea side are title contenders, and rather than beat themselves up, the Clarets must look to every silver lining in order to build momentum for the rest of the season.

Jenni in Newtownards: Cesc Fabregas will be the Chelsea player who gets all of headlines and the praise, but he is only allowed to shine because of the work-rate, industry and the often unseen work of his midfield partner Nemanja Matic. Without him holding things together in front of the back four, Chelsea and Fabregas wouldn't look or play the same way. Matic is definitely the unsung hero of the side.

Elsewhere, it's been raining goals in Scotland with Rangers cruising into the third round of the Petrofac Training Cup with an 8-1 win over Clyde at Ibrox. A crowd of 11,190 witnessed Kris Boyd help himself to a hat-trick and Lewis Macleod and current captain Lee McCulloch each score two. Fraser Aird scored the other, while Kevin Watt cracked in a last-minute consolation for Clyde.

Kev Mcveigh:, external Chelsea have never relied heavily on strikers, they get goals from midfield and defence unlike some teams.

Ken Gorry:, external Mourinho's biggest job is going to trying to keep players happy, Willian and Salah turned down other clubs to go to Chelsea.

Edd Wilkinson:, external Am I the only one to notice Chelsea's lack of depth in defence? Filipe Luis is the only quality back up to this starting back four.

"Diego Costa has got some fire in his belly, a bit of a dark side and looks like someone who will bully opposition defenders. It was a really promising start from him. It was a nice and composed performance from Thibaut Courtois as well. I like my goalkeepers to be calm, and he was a picture of that. He looked like he'd been playing in the Premier League for years."

John Terry tells Sky Sports: "Jose has made some very big signings this summer like Costa who was different class tonight the way he held the ball up, we're hoping to win the league this season.

"It will be very tough but it was important that we got three points."

Cesc Fabregas tells Sky Sports: "You always want to do well and I love playing football, we have a very talented young team and so far so good.

"Everyone has treated me very well and I'm enjoying it here. Everyone has made it so easy for me, the staff, the players. It was something I would never have expected, football has brought me here and I will give my best to make it work for me and Chelsea."

"Chelsea never gave Burnley a sniff in the second half and Sean Dyche's side lacked that bit of quality. But it was not for want of guts, spirit and application. Tonight they will have learned how important it is to keep the ball against the top sides."

Jose Mouirnho trudges across the Turf Moor pitch towards the tunnel. He doesn't look totally thrilled. Maybe he should take a look at the table to cheer himself up. Chelsea are top!

Meanwhile, Didier Drogba walks over to salute the travelling support. He whips off his shirt before throwing it into the crowd. Someone is going home with a special souvenir.

A tough return to the top-flight for Burnley. An all too comfortable start to the new season for Chelsea.

Vintage Didier Drogba as the Chelsea substitute lets fly from outside the area with a right-foot volley after controlling the ball with his thigh. It flashes narrowly wide. Sublime effort.

Duncan in Richmond: People may say 'it's only Burnley' but we all remember Cardiff beating Man City last season and Liverpool crumbling at Crystal Palace. The league is won and lost at places like Burnley on wet Monday nights. You can bet your bottom dollar than one of the big boys will slip up against one of the so called lesser teams somewhere down the line!

Steve in Surbiton: Good team Chelsea. Let's see them play Liverpool and Man City first though. Although I bet United are not looking forward to playing Chelsea.

Rui in Hoxton: If Fernando Torres and Didier Drogba could have played together at their peak, there would be no defence in this era, any era past or any era future that could have dreamt of dealing with them. Tis a shame that it is only their ghosts at Turf Moor tonight.

Marvin Sordell was sent on by Sean Dyche in an effort to haul Burnley back into this. But the substitute ends up picking up a yellow card for clattering into John Terry which sparks loud cheers from three sides of Turf Moor.
