Manchester United's Alexis Sanchez misses Brighton clash through injury

BRIGHTON, England -- Manchester United manager Jose Mourinho has been dealt an injury blow with the news that Alexis Sanchez has been ruled out of Sunday's game at Brighton.

Sanchez, 29, did not travel with the team on Saturday afternoon after picking up a problem in training and is now a doubt for Tottenham's visit to Old Trafford on Aug. 27.

"Alexis was going to play but he had a little problem," Mourinho said before the game. "So we had to decide to give an opportunity to another attacking player."

Mourinho welcomed Nemanja Matic and Antonio Valencia back to training after injuries, but the trip to Brighton came too soon for them to be included.

Valencia suffered a calf injury during preseason while Matic underwent surgery on an abdominal injury picked up during the World Cup. Both are in line to return to the team against Tottenham.

In Sanchez's absence, Mourinho handed Anthony Martial his first start of the season against Brighton while Romelu Lukaku also returned to the team after being named on the bench for the Premier League opener against Leicester.
