Premier League trio Everton, Newcastle United and West Ham United have been linked with a move for the Cape Verde international Garry Rodrigues.
However, Galatasaray officials are worried that the interest in their star man has affected his performances.
The pacy winger’s form has suffered a slight dip in recent weeks, which may prove costly going into the business end of the season.
According to the Turkish outlet Fanatik, Galatasaray are concerned that Rodrigues’s head has been turned by a potential move to the Premier League.
The 27-year-old has failed to register a single goal or assist in his last five appearances for Galatasaray.
We recently reported that Galatasaray rejected a £10 million bid from West Ham for Rodrigues and that Everton and Newcastle United are also interested.
The Cape Verde international has provided nine assists and scored six goals in 25 Turkish Super Lig appearances for Galatasaray this season.
