Away we go! Chelsea kick us off.

No reaction really from the home crowd to Jose Mourinho taking his seat in the United dugout. His place in the Stamford Bridge record books was assured long ago. At Old Trafford? Maybe not so much.

Kick-off fast approaching at a sunny Stamford Bridge. Plenty in unseasonable short shirts in the crowd. Brave call.

Are Chelsea about to head to the top of the league, if only for a few hours?

Manchester United have lost more Premier League games against Chelsea than against any other side (18), and the Blues are one of only two sides the Red Devils have lost more games against than they’ve won in the Premier League, along with Brighton.

Chelsea lose their edge without Eden Hazard. He is one of those players that comes along once in a generation. He's capable of breaking down a formation set up to stop him.

There aren't many like him.

And yet Mourinho has picked an attacking side with Herrera and Fred on the bench, McTominay and Fellaini not included at all...

Does anyone really think Man United will go out and attack Chelsea today? I wouldn’t have thought so. Mourinho will be parking the bus.

It’s not the swashbuckling Manchester United of old, it is not the same.

Every team in the world would want to take Hazard. He is the form player in the Premier League, the goal he scored against Liverpool in the Carabao cup showed the talent.

He is looking better every season, he has a free role under Sarri, given more freedom and the team is built around him. Built to get him into the game.

What Jose Mourinho would have ideally wanted after his team's dramatic comeback against Newcastle was another home game in quick succession to try and build some much-needed momentum.

Instead, after a fortnight's wait he has a return to Stamford Bridge, where he has lost on every visit since he left Chelsea for a second time.

It will be fascinating to see if Manchester United can use the remarkable second-half performance at Old Trafford in any way to dent Maurizio Sarri's impressive start to his tenure in west London.

Chelsea are seven points better off under the Italian than they were 12 months ago and have implemented the new coach's philosophy instantly.

The first managerial meeting of Messrs Sarri and Mourinho is full of intrigue.

There's many teams, Chelsea included, that will have had players spread across the world and it's part of big club mentality to manage the international break as best you can.

Alvaro Morata came on late for Spain against England but Olivier Giroud played the whole game for France.

Michael Mugford: When Giroud shows his individual career highlights to his kids and grandkids, they're going to think he was the best player ever. Worldies and majesty. Morata on the other hand is poor man's Fernando Torres.

Kelvin Okoro: Am a Chelsea fan, but something just tells me this will be a Manchester United win. Hope it’s not.

Babyboomer: When it comes to defensive headers in the penalty area, Man Utd's four centre backs are the weakest in the country. Chelsea could score a hat-trick of headers.

Afternoon from the Bridge, there’s much anticipation round here and some interesting team selections. I’m surprised Alvaro Morata replaces Olivier Giroud up front, I know Giroud is yet to score this season but he offers so much to those around him.

It looks like Jose Mourinho is going for a 4-2-3-1, Ander Herrera is on the bench and Juan Mata starts on his return to Stamford Bridge.

It will be interesting to see how Jose Mourinho approaches this. Will he try and stifle Chelsea? Can they stop Eden Hazard and maybe just as importantly Jorginho?

Jose Mourinho appears to have reached the stage at Manchester United where his future can be debated after every game - so he will want a big result on his return to former club Chelsea.

Mourinho's second Chelsea reign ended in what the technical director Michael Emanalo described as "palpable discord" between players and manager.

It does not appear as if everyone has been singing from the same songsheet at Old Trafford this season so Mourinho, spared further speculation by that dramatic 3-2 win against Newcastle United, must conjure up some of the old Stamford Bridge magic today to build on that momentum.
