Van Persie and Rooney unavailable for Swansea clash.

Manchester United will once again be without Robin van Persie and Wayne Rooney for the visit of Swansea City on Saturday.

The Dutchman has not featured for the club since 10 December due to a persistent thigh problem while Rooney missed United's consecutive cup losses to Swansea and Sunderland with a groin injury.

Moyes explained that the England international will be sent on a hot weather break in the hope of accelerating his recovery time in time for the trip to Chelsea on the 19 January, but the Scot was unable to provide a predicted return date for van Persie.

"With Wayne we've sent him away on a hot-weather break," Moyes said in a press conference, United's official website reports.

"His groin isn't quite recovered yet so we've sent the fitness coach with him and he's away with his family. It will give Wayne a bit of a break.

"We always hoped to be able to do it at some time in the season and the groin is not as good as we had hoped. Hopefully we can get him fit for the Chelsea match but we'll see how he is. He's away and will do some work with the fitness coach.

"Robin is going to be a little while. We'll do everything we can to get him back quickly. Wayne has got an injury and we have to hope for that, but we'll see how it goes. It's probably the right time to give it a chance to heal.

"We thought the best thing was to get him to the warner weather with one of the coaches and spend time with the family as well. Hopefully it will make him better."

To continue a forgettable week for the club, Moyes has been charged by the Football Association for misconduct in a charge relating to his comments following his side's 2-1 defeat to Sunderland in the first leg of their Capital One Cup clash with Sunderland.

The United manager was riled at the decision that led to Fabio Borini scoring what turned out to be the winner from the penalty spot. He will have until 6pm on 15 January to respond to the charge.
