Liverpool are intensifying their interest in VfB Stuttgart winger Filip Kostic.

BILD says Liverpool boss Jurgen Klopp is shopping in Germany for a new winger this summer and has had Hoffenheim attacker Kevin Volland watched.

However, Kostic's progress has convinced Klopp to step up their watching brief on VfB star Kostic.

The Serbia international has moved to the top of Klopp's shortlist thanks to his outstanding goalscoring form this season.

Kostic is tied to VfB to 2019.
