West Ham United are looking to improve their attacking options in the summer and have identified Adam Hlozek as a target.
According to 90min, the Hammers have stepped up their pursuit of the 18-year-old striker.
West Ham sold Sebastien Haller to Ajax during the January transfer window and are yet to bring in a quality replacement.
They cannot rely on Michail Antonio as their only striker next year, and signing a goalscorer is their top priority.
According to the report, Bayern Munich, Juventus and Borussia Dortmund are also keeping tabs on the player.

Hlozek has the potential to develop into a top-class striker in future and could prove to be a superb long term investment for the London club.
The opportunity to play alongside compatriots Tomas Soucek and Vladimir Coufal could help the Hammers sign the Czech hot-shot this summer.
West Ham are in a good position to secure Champions League football, and that would also improve their chances of landing elite talents like Hlozek.
The striker could be available for a fee of around €30 million. He has five goals and seven assists in 14 appearances for Sparta Prague this season.
Despite the considerable interest in the player, the Hammers have a key advantage.
Bayern and Juventus may not be able to provide him regular first-team football, and the Hammers could lure him with game time assurances.
