Cristiano Ronaldo is back as Manchester play 1-1 draw in the final game.
Cristiano Ronaldo returned to Manchester United as the team played 1-1 with Rayo Vallecano at Old Trafford.
Ronaldo who was absent from his tour to Thailand and Australia because of an issue with his family, was the first player to start the game, but was replaced after 45 minutes.
The 37-year-old was given a chance in the first half, but shot over the crossbar.
The substitute for his half-time slot, Amad Diallo, gave United the lead just after the break. However, Alvaro Garcia equalised.
Ten Hag selected a mixture of youngsters and fringe players against Rayo.
Both Martinez and Eriksen were withdrawn in the second half before Ten Hag made his debut to 17-year-old midfielder Isak Hansen in the closing minutes.
