Liverpool have been put on alert after Filip Kostic cast doubt over his future by snubbing a new contract with Stuttgart.

The Reds have scouted the 23-year-old winger on several occasions this season with a view to making a summer bid and a move now looks more likely after he rejected fresh terms.

Kostic has made it clear to Stuttgart he wants to play in European competition next season and has attracted interest Borussia Dortmund, Schalke and Wolfsburg.

But, according to Bild, Kostic would be open to a move to the Premier League and Liverpool are leading the chase for him.

However, the Merseyside club will have to pay a fee of around £24million for the Serbian.
