Manchester United announced Monday the club had "immediately rejected" a second Chelsea bid for striker Wayne Rooney.
The bid was for about 25 million pounds ($38.4 million) according to reports.

United reiterated Rooney, who has two years remaining on his contract, is not for sale: "Our position remains that he is not for sale."
Chelsea manager Jose Mourinho said in July that the club had made an official bid for Rooney. The London club was moved to confirm the bid to deny that it had offered midfielder Juan Mata or defender David Luiz as part of a 10 million pound ($15 million) offer.
Rooney has sought an exit from United after publicly expressing frustration over reduced playing time last season.
United also reported Rooney's injured right shoulder would prevent him from traveling to Sweden for a pre-season match against AIK in Stockholm on Tuesday.
From the Associated Press:
"Wayne hurt his shoulder in a fall during a match on Saturday,'' United manager David Moyes said. "It's not too serious and I don't expect it to keep him out for too long. I'm disappointed he's missing the game because we were keen to get him back involved and ready to play.''
