Chelsea manager Jose Mourinho has claimed that Manchester United should not worry about selling Wayne Rooney to a rival club.
The Blues have already failed with two bids for the England striker, but they are expected to make a third offer after the two teams meet at Old Trafford in the Premier League on Monday.
"To me it is not a difficult decision because you want very much to keep Rooney or you don't want to keep him," Mourinho is quoted as saying by Sky Sports News. "But that old-fashioned mentality of, 'I don't sell players to clubs in the same country' - I think doesn't help.
"Sometimes you push players abroad when you should be keeping them in your league because then you are contributing to making your league the best league."
United boss David Moyes has repeatedly insisted that he is not willing to sell Rooney.
