Manchester: Manchester United manager Ole Gunnar Solskjaer admitted his decision to risk Marcus Rashford as a second half substitute "backfired" despite seeing his side progress to the fourth round of the FA Cup with a 1-0 win over Wolves on Wednesday. Rashford lasted less than 15 minutes on the field due to a back injury and is now a doubt for the trip to runaway leaders Liverpool in the Premier League on Sunday.

The brief cameo from United's top goalscorer coincided with the only goal of the game as Juan Mata's clinical finish ensured United will travel to either Watford or Tranmere on January 26th. "That backfired, but you've got to go for them," Solskjaer said. "He's got a knock and couldn't run. Let's test him for Sunday and see how he goes. He's had a few knocks with his back lately and he got another one."
