Werder Bremen have confirmed that they have received no bids for their Brazilian playmaker Diego.
The 23-year-old has recently been linked with a move to Juventus with manager Claudio Ranieri publicly declaring his interest in the midfielder.
The former Porto man, who signed from Bremen in 2006 for 6million Euros following an unsuccessful stint in Portugal, has also been rumoured to be attracting interest from Manchester City
The 2007 Bundesliga player of the year may fancy a switch to Eastlands to link up with friend and former team-mate Robinho after the pair came through the ranks at Santos together, but the club have dismissed the rumours.
"We have not received any bids for Diego and yet again we do not want to get rid of him," club general manager Klaus Allofs told Bild am Sonntag.
"He is not for sale and has a contract until June 2011. We want to keep him as long as possible."
Diego has been making headlines off the pitch recently giving his club cause for concern.
The Brazilian international was caught drink driving and was sent-off for slapping an opponent in December triggering the club to monitor his behaviour.
It has been reported that the midfielder, who has scored 34 goals in 74 Bundesliga games in his role behind the strikers, has grown frustrated with life at Bremen.
With the club eighth in the league and out of the UEFA Champions League at the group stages it has been mooted that their star wants out.
"Diego is a full professional and a good ambassador for Werder," Allofs maintained.
"However, he is part of our team and we are clearly monitoring him. He has an obligation to fully help the team with good performances and attitude. We want to be successful."
