Bayern Munich are poised to make a move for Schalke's Brazilian playmaker Lincoln, according to the German press.
The Bundesliga leaders are looking at the 27-year-old as a replacement for German international Michael Ballack, it was reported in Bild.
Schalke coach Mirko Slomka has publicly criticised his player's form, despite an 11-goal return from the attacking midfielder this season, and subsequently dropped him for the side's Uefa Cup first leg semi-final with Seville.
Though he was brought on for the second half in the 0-0 stalemate in Gelsenkirchen, Schalke team manager Andreas Muller has admitted there has been a problem with the player.
"We are doing everything possible to improve our relationship with him again," he told Bild.
"At the moment we have no intention of letting Lincoln go, although I know that he has the class to replace Michael Ballack," he said.
Ballack's contract at The Allianz Arena runs out in the summer, while Lincoln is contracted at The Veltins Arena until June 2008.
The Brazilian is likely to cost around é¼10 million, should Bayern make the move.
