LOS ANGELES. Chelsea have not given up hope of signing unsettled Manchester United forward Wayne Rooney, Blues manager Jose Mourinho has said.The Premier League champions have already turned down a bid for Rooney, who is believed to be unhappy at the club where he has won five league titles and the Champions League in 2008.United have maintained that the 27-year-old is not for sale, but Mourinho said following a pre-season loss to Real Madrid in Miami on Thursday that they would continue their pursuit."We are far away so we are not in England to know every detail but we are doing things in the correct way,” Mourinho told reporters in America."We made the bid and Manchester United have reacted. Let’s see what happens. But we can’t do more than we are doing now."We are doing things legally, making the official bid directly to the club, no interviews or comments or direct relations with the player, no contact, absolutely nothing."We are doing everything in an ethical way, so let’s see if things change,” added Mourinho, who was fined by the Premier League in 2005 for tapping up Ashley Cole prior to the defender’s transfer from Arsenal during his first stint in charge of the Blues.Mourinho also said he had no interest in selling Brazilian defender David Luiz to Barcelona and was happy to be patient over Rooney, with Chelsea already boasting a strikeforce of Fernando Torres, Romelu Lukaku and Demba Ba.
