Heerenveen's free-scoring winger Danijel Pranjic could be on his way in the summer.

The Croatia international has been in stunning form this season and is being watched by the likes of Portsmouth, West Ham, Manchester City, Sunderland and Newcastle.

"This is the fourth season I've had here and it's the best I have ever played," said Pranjic.

Dutch sources say Pranjic could make the move away from Heerenveen at the end of the season, though he has pledged his commitment to the club.
