West Ham United have reportedly entered the race to sign Blackburn Rovers midfielder Bradley Dack in January.
Dack's performances for Blackburn so far this season have attracted the attention of a number of clubs, having scored 11 and created six more in 19 appearances across all competitions.
The Birmingham Mail reports that West Ham are among the interested parties as they look for a creative midfielder as cover for Manuel Lanzini, who has missed the entire season so far through injury.
The Hammers are thought to be planning a bid of around £20m, although Blackburn are reluctant to sell their star asset midway through the season.
Crystal Palace are also understood to be tracking the 24-year-old, while there is interest from fellow Championship club West Bromwich Albion too.
Dack only joined Blackburn from Gillingham last year but helped fire Rovers to promotion during his debut season with 18 goals in League One.
