Premier League clubs are circling Sporting CP for Bas Dost.
The big Dutchman has enjoyed a superb season in Portugal, challenging for the European Golden Boot.
Rome sources say Lazio are interested in Dost, but face stiff competition from England.
Everton, Stoke City and West Bromwich Albion are also interested in the centre-forward.
Dost finished the season with 34 goals after his hat-trick against Chaves on the weekend.
