According to reports in the Guardian, Sergio Ramos has been told that he will not be sold under any circumstances by Real Madrid, following a meeting with Real president Florentino Perez.
Manchester Untied have twice bid for Ramos this transfer window, with their last bid being around £40 million. United have informed Real that unless they are sold Ramos for a fair price, they will not allow goalkeeper David de Gea to join them this season. United expect De Gea to leave on a free transfer at the end of next season, and have lined up Ajax's Jasper Cillessen as his replacement.
At the meeting, Ramos again said that he wanted to leave for Manchester United, which goes some way to strengthening their hand in the De Gea negotiations. With Nicolas Otamendi a potential replacement for Ramos should he leave, and a target for United should they fail to land Ramos, this transfer could run for some time yet, so it does not yet seem a move to United for Ramos is even close to likely.
