Adnan Januzaj, farmed out on loan to Borussia Dortmund by Louis van Gaal, is watching from Old Trafford's directors' box as Manchester United make a very bright start here.

Only the woodwork has denied them and they are playing the sort of high-tempo attacking football their fans demand.

United are playing with a real sense of purpose and desire - ingredients which have been missing for so many of their games this season.

"It's a different United we are witnessing, quicker and with more purpose. It's the sort of thing the fans at Old Trafford want to be seeing.This is more like the Manchester United of old."

United hit the woodwork AGAIN! Anthony Martial is a box of tricks on the edge of the Chelsea penalty area, before cutting inside and firing past Thibaut Courtois, but the ball rebounds off the post. How much longer will Chelsea hold out?

"The tempo they are playing at, I don't know how long Manchester United will keep it up for. They are all over Chelsea at the moment. Now they need to make it count."

The game has settled after such a lively start. Oscar gives away possession inside his own half but the hosts can't capitalise. Ashley Young, at right-back, and Matteo Darmian, on the left, are causing the visitors problems on the overlap.

United have done more in the opening 10 minutes here than they did in 90 at the Britannia Stadium on Saturday.

Old Trafford may have been subdued before kick-off but it has come to life in these early minutes after a bright and energetic start from Manchester United.

Chelsea are not standing back and it took that superb save from United keeper David de Gea to deny John Terry.

Lively stuff.

First on Match Of The Day tonight, Gary?

Another United chance and Morgan Schneiderlin fires a shot narrowly wide with a first-time effort from outside the area. United are up for this. It's a complete contrast to their start at Stoke on Boxing Day.

Chelsea, all in blue, are attacking the Stretford End. More television replays of David de Gea's save to deny John Terry. It gets better and better.

This is already turning into a Christmas cracker. Both teams might be struggling but both could already have early goals. It's frantic end to end stuff.

"If you look at Chelsea, they have set up for the counter attack. They will think if they can get the the lead they will be good enough to hold on to that."

Brilliant save by David de Gea to keep out John Terry's header from a corner. The United keeper shows stunning reflexes to stick out a hand and push the ball over. What a start to this game.

Juan Mata might have been denied by the bar but that effort has got the crowd going.

"Van Gaal's made a few changes, Darmian coming back is a plus - even if he is playing on his weaker flank - and there's a better balance to the sides. He has a lot of experience out there. He is hoping the senior players can drag the younger players through."

Huge roar as John Terry concedes an early throw-in. Seconds later Juan Mata hits the crossbar with a thumping effort after a great pass from Wayne Rooney.

Just the start Louis van Gaal wanted.
