Madrid: Kaka's future at Real Madrid is still up in the air, coach Jose Mourinho said on Friday, adding that he would be delighted if the Brazilian playmaker stayed with the La Liga club."I don't know if he will stay or not, and neither he nor the team know either," Mourinho said at an awards ceremony in Lisbon."There are no doubts between us, he knows what I think and I know what he thinks," added the Portuguese, according to the Real website (www.realmadrid.com). "As long as he is our player, and it’s possible that he will stay another season, he will contribute."If he stays I’ll be delighted and he will come to the U.S.” on our pre-season tour.Mourinho included 2007 World Player of the Year Kaka in his squad for Real’s friendly at Benfica later on Friday but the 30-year-old is widely expected to move on after three largely disappointing seasons in the Spanish capital.He has shown flashes of his former brilliance since joining from AC Milan for around 65 million euros but has been sidelined several times by injury and mainly played second fiddle to German international Mesut Ozil last season.He has been linked in media reports with a move to Paris St Germain, the Ligue 1 club coached by his former boss at Milan Carlo Ancelotti, as well as a loan deal back to Milan and even a move to MLS side New York Red Bulls.
