Wigan Athletic have captured striker Conor Sammon on a three-and-a-half-year deal from Kilmarnock for an undisclosed fee on transfer deadline day.
The 24-year-old becomes Latics boss Roberto Martinez's first permanent signing of the transfer window in a deal completed just minutes before the 11pm deadline.
Sammon has netted 24 goals in 64 SPL appearances for Killie, including 15 in 20 starts this season to help the club to fourth place in the Scottish top flight.
And Martinez has expressed his delight in catching the Irish frontman, telling the club's official website: "Conor is a young, hungry player we have been looking at for a while.
"He has developed in an incredible manner over the last six months and it's fortunate that we've been able to move for him before he has achieved his full potential, which we're hoping he will do in a Latics shirt. We are delighted to welcome him on board."
Dublin-born Sammon, whose arrival has come too late to see him feature in the squad to face West Brom in the Premier League on Tuesday night, admitted it had been a wrench to leave Killie.
The former Republic of Ireland Under 21 international said: "It was a big decision to leave a club that has been so good for my career but I'm a Wigan Athletic player now and I want to prove to everyone here they've made the right choice, and prove myself in the Premier League."
Martinez added that the arrival of Sammon, who will wear the number 18 shirt at the DW Stadium, concludes a satisfactory month in the transfer market.
The Spaniard, who turned down Newcastle United's 11th hour £10million offer for Charles N'Zogbia, said: "Our main priority was to finish January stronger than when the window started.
"We've achieved that by keeping our best performers, who attracted well deserved attention within the game and we've got real satisfaction to be able to retain the services of Tom Cleverley and Ali Al Habsi until the end of the season, which is a major positive for us.
"The return of James McCarthy, Franco Di Santo, Victor Moses and Emmerson Boyce after long-term absences all feel like fresh signings into the squad.
"The fans can be proud and excited about the challenge ahead."
