Eight changes for United. Darmian switches full-back positions, Martial and Fellaini also stay on.

Away we go in the second half.

Lots of changes for Manchester United too. Romelu Lukaku and Paul Pogba are among them.

Real Madrid are going to change their entire XI we think at half-time. I'll try and confirm the new team when I can...

Will Jose Mourinho add to his squad before the end of August? And if so, who will come in?

That type of skill is the reason why United paid such a huge sum for Anthony Martial, and also why he is so frustrating.

His time at Old Trafford is littered with moments like that. But along with them come days when the Frenchman is anonymous.

It has been suggested Martial might be used as a makeweight in the deal to get Ivan Perisic from Inter Milan.

United want to be certain they couldn't get more from Martial before they let him leave because if he can find consistency, he can be brilliant.

We all miss football Jay...

Jay: Bailly & Jones are playing brilliantly in defence. Lingard, Martial & Pereira are playing amazingly. Great to watch this match

United lead at half time then in Santa Clara.

Brilliant again from Luka Modric. A class act. First he plays a through-ball from the centre circle which Phil Jones does well to clear before popping up on the right wing and threading a cross into the middle, which Sergio Romero clears away smartly.

A flurry of action as the half draws to a close, Jesse Lingard carries the ball at pace and shoots on the run, from 22 yards, it swerves away from Keylor Navas but just past the post as well. Good effort!

Real have a three-on-three breakaway but Lucas Vazquez makes a mess of the final ball, as does Anthony Martial at the other end moments later.

Is this a big season for Anthony Martial? His Manchester United career is in danger of peaking on his debut at the moment.

It was interesting to note just then the Manchester United players were all given towels to put on the back of their necks to cool them down on what is a pretty hot day.

There is clearly a positive impact of that, as there will be from going into the small pool United had installed next to their training pitch at UCLA,

Time in it was strictly controlled but it was another indication to what extent footballers are pushing the boundaries in a search for marginal gains.

Karim Benzema beats a man and thinks about getting a shot away but he's closed down by Eric Bailly. Andreas Pereira, best player out there so far, then does well to beat two men and keep the ball on the right wing.

Memories of John Aldridge as the players have a drinks break in the intense Californian sun. Some Manchester United staff drape some sort of towels on their players too.

The game is only really being played at walking pace but it is properly hot.

I can't believe I missed the fact that the teams shook hands with Ronald McDonald before kick-off. Surreal!

Real Madrid now dominating possession but there's very little in the way of goalmouth action to report. Both clubs getting minutes under their belts, and that's about all so far.

Real Madrid and Manchester United are on the same pitch today and they have been training pretty close to each other over the past week or so.

Both clubs have been using the impressive facilities at the UCLA campus in Los Angeles, with their pitches less than 200 yards apart.

One day last week, Marcelo was spotted with his family at the hotel United's staff are staying in.
