Chelsea Football Club confirmed today that they put in a written offer for Manchester United striker Wayne Rooney yesterday, but the bid did not offer a player as part of the deal.

It was reported earlier today that Chelsea put in a £10million bid for Wayne Rooney plus either Juan Mata or David Luiz. However, The Guardian newspaper are reporting that Chelsea’s bid for Rooney was £20million, and that the London-based club are furious that the details of the transfer bid were leaked to the media.

Sources close to United also reveal that Mata or Luiz could come as part of the package deal.

Manchester United have yet to make an official comment regarding any of the developments.

Chelsea manager Jose Mourinho said yesterday that he has no plans to sell any Chelsea players this summer. And Mata or Luiz are two prized assets that the Stamford Bridge club will want to hold on to. But the opportunity to secure Rooney could be tempting enough to allow either Mata or Luiz to leave.

The ball is now back in Chelsea’s court to see if they, or another club, will put in a higher bid for Wayne Rooney.
