Sheffield Wednesday have signed Watford forward Fernando Forestieri for an undisclosed fee and brought in Hornets defender Daniel Pudil on loan.
Italian Forestieri, 25, has agreed a four-year contract while Czech Pudil, 29, will be with the Owls for the rest of the season.
Forestieri scored five times in 26 outings as Watford were promoted to the Premier League last season.
However he has featured just once, in the League Cup, in the new campaign.
The ex-Udinese player came close to joining Leeds this week but Whites chairman Massimo Cellino claimed he did not have the "right mentality" to play for the club.
In total he scored 21 goals in 91 appearances during his spell at Vicarage Road.
Pudil, who has not featured in any of the Hornets' games since their promotion to the Premier League, has featured 108 times after joining from Spanish side Granada in the summer of 2012, initially on loan.
The Czech Republic international is the second defender to move to Hillsborough on loan from the Premier League club this week after Norwich's Michael Turner agreed a season-long loan on Thursday.
