MADRID, August 16 (Primera Liga) - Coach Bernd Schuster is convinced Robinho will stay with Real Madrid and has again insisted he sees no problem with the Brazilian's attitude despite persistent speculation that he wants to leave the Spanish giants. Robinho's agent Wagner Ribeiro recently claimed the winger was 'very angry' with the way he feels he has been treated by Madrid and was keen to move to Chelsea, who made a formal offer for the 24-year-old - believed to be in the region of £20 million. Madrid rejected that bid and insist Robinho is not for sale, but speculation about the Brazilian's future is still rife in Spain, with contrasting reports about his current situation. Some reports suggest the player refused to travel to Valencia for the first leg of the Spanish Supercopa on Sunday, while others claim Robinho is ready to stay at the Bernabeu and is about to sign a new, much improved contract. Schuster gave his response to that speculation on Saturday, saying: 'Right now I'm sure that Robinho will stay. For me it is not a problem and I'm not going to worry about it because he is going to be our player. It is not a concern.' The German coach, who was speaking after including the former Santos ace in his 18-man squad for the trip to Valencia, added: 'At no point has Robinho given the impression that he does not want to go (to Valencia). 'He is very well. I have spoken with him and the player is in perfect shape. 'He is training normally, is here to play and therefore he is going to play. 'I can only assess what Robinho does here, and with us everything is normal. In the games he has played in pre-season he has done very well, played with a lot of joy, and it's the same in training,' added Schuster, echoing comments he made before Tuesday's friendly against Eintracht Frankfurt. 'I have to say that I haven't seen any change in his attitude.'
