Manchester United midfielder Carlos Baleba will miss a few weeks with a hamstring injury picked up in Tuesday's 3-2 Champions League win over AS Roma, manager Michael Carrick said on Friday. Carrick noted, "It'll be a little bit longer than that," as the team also faces a tough winless league run.

A hamstring blow ahead of the Aston Villa game, a defensive doubt and a long winless league run leave United short on options as the international break now approaches.

Manchester United midfielder Carlos Baleba will miss a few weeks with a hamstring injury picked up in Tuesday's 3-2 Champions League win over AS Roma, manager Michael Carrick said on Friday.

"It's definitely not this week, and he won't be back at any point over the international break. It'll be a little bit longer than that," Carrick told reporters.

Carrick also said left back Patrick Dorgu is still a doubt for Sunday's Premier League game against Aston Villa, even though he is back in training after a hamstring problem.

United are 17th in the league and are looking for their first Premier League win since August.
