A reception fit for a returning hero. Chelsea fans rise as Didier Drogba comes on for the final few minutes. His last touch in a competitive game for Chelsea? The penalty that clinched the Blues the 2012 Champions League.

"It's going to be hard for Burnley to survive in the Premier League. They will have energy and work hard, but it's just that bit of quality they need. When a team comes up you wonder where are the goals going to come from. That's the key for Burnley as well. Danny Ings got a lot of goals in the Championship last season but it's a big step up. Will the likes of Lukas Jutkiewicz, Ashley Barnes and Sam Vokes find the net enough?"

This is Cesc Fabregas's first Premier League appearance since turning out for Arsenal in a 2-1 defeat at Bolton in April 2011. It's been a performance to savour. Full of running, full of imagination and creativity. The changes are coming thick and fast. John Obi Mikel is on for the visitors, while Marvin Sordell has come on for Burnley, replacing Danny Ings.

"You know when some players move and just look wrong in their new kit? Cesc Fabregas doesn't. I know Gooners may disagree though."

This game is over as a contest but few home fans are leaving. After all it has been four years since the locals have seen their team in the Premier League. Andre Schurrle receives a standing ovation from Chelsea's travelling fans as he makes way for Willian.

Former England wicketkeeper and Chelsea fan Alec Stewart on Twitter:, external "Great to see Cesc Fabregas doing the Chelsea number four shirt justice already. Quality performance so far."

Full-time in the pre-season friendly at the Nou Camp and it was an easy peasy 6-0 to Barcelona in their match against Leon. Neymar got a couple, Lionel Messi was on the scoresheet and, with roughly 15 minutes left, Luis Suarez came off the bench to make his debut after signing from Liverpool in the summer.

"Chelsea have probably been playing within themselves for the majority of this half. The job was pretty much done in the first half."

The clock is ticking and Sean Dyche makes a double substitution in an effort to haul his Burnley side back into this. New signings Lukas Jutkiewicz and Matt Taylor make way for Ashley Barnes and Michael Kightly.

BBC 5 live will be paying tribute to James Alexander Gordon tonight from 22:00 to 22:30 BST.

Gordon, one of the most recognisable voices in British broadcasting, has died aged 78. He read the classified football results on BBC radio for 40 years before stepping down in 2013.

We'd especially love to hear your memories of him reading the classifieds - you can do so by texting 85058 or Tweet @bbc5live

So Robbie Savage's tweet that he's watching the champions has not gone down well with everyone. There's no doubt bigger tests lie ahead. But make no mistake. Their response to falling behind has been impressive. Very impressive.

Ed in St Ives: Any bets that the current top four will be the final finishing positions at the end of the season?

Jon in Manchester: Robbie Savage saying he's watching the champions. After one game? At newly promoted Burnley? Maybe he should join his hair in the museum.

Hassan in London: I think you may be getting carried away. Yes, Chelsea have depth that was previously lacking and may well be favourites to win the league with Man City. But calling them champions based on the first game of the season against newly promoted Burnley is poor.

"Danny Ings has not had much service and he's been up against a strong Chelsea defence. It's a steep learning curve for him, and a steep one for Burnley. But their ability to survive in the Premier League won't be defined by games against the top side Chelsea. It will be the matches with the teams in and around which will matter."

Burnley fans are out of their seats as Matt Taylor stretches for a cross but the former West Ham player is unable to connect. The story of Burnley's night.

"Nemanja Matic has really impressed me for Chelsea. He's been a bit below the radar but has hardly misplaced a pass all night."

It's all a little bit too easy for Chelsea. It's like a pre-season friendly as blue shirt passes to blue shirt. Then another blue shirt to another blue shirt. Burnley started well this half but there's only one team in control with half an hour remaining. Can the Clarets haul themselves back into this?

And here he is, not spotted on a football pitch since his biting antics at the World Cup, Luis Suarez off the bench for his Barca debut in their pre-season match against Leon.

Nice and easy too, with his team 4-0 up and coasting with roughly 15 minutes left.

Big cheers for the Uruguayan as he made his way on.

Out comes the vanishing spray as Eden Hazard wins Chelsea a free-kick after being hacked down by David Jones 25-yards out. Shame about Andre Schurrle's effort which sails high and wide. Burnley breathe again.

Options, options....if Jose Mourinho wants to change things at any point in the second half he certainly has plenty of quality on the bench, particularly in midfield and going forward. Willian, Jon Obi Mikel, Fernando Torres and one Didier Drogba - take your pick Jose.
