We have visited the mid-season training camp of Manchester United at Doha/Qatar and want to present an insight into that specific session.
Unfortunately we were not able to attend the entire session, however we have observed ~20 minutes warm-up and ~20 minutes of different games.
The video below shows the warm-up drills, the stretching and another (more intense) warm-up part.
After the entire warm-up the team played 7 vs 7 +1 on the pitch (please see Figure below - part 5).
The first game was ~8 minutes in length and was played without goalies for possession.
Unfortunately we had to leave after that, however, the goalies joint in for the next game.
