Aston Villa have signed Scott Hogan from Championship rivals Brentford for a fee that could reach £12m.
Hogan, linked with a move to Premier League side West Ham, has scored 21 goals in 34 games for the Bees after joining from Rochdale in July 2014.
The League One side are due 30% of any fee received for the 24-year-old.
Aston Villa were beaten 3-0 by Brentford at Griffin Park on Tuesday, two hours before Hogan's move was confirmed.
Villa have been busy during the transfer window, with Nottingham Forest captain Henri Lansbury, Barnsley skipper Conor Hourihane and Iceland international Birkir Bjarnason among their other January signings.
