Derby have completed the signing of striker Conor Sammon on a four-year deal after agreeing an undisclosed fee with Wigan Athletic.
Sammon makes the move to the Championship club having struggled to establish himself in the first XI during his 18-month stay with the Latics.
The former Kilmarnock forward made the move to the Premier League in January last year, but managed just one top-flight goal from 32 appearances, with 23 of those coming from the bench.
Rams managed Nigel Clough was keen to sign Sammon in 2011, only to lose out to Wigan in the chase for his services and was happy to finally get his man.
Clough told the club's official website: "When we first drew up a list of potential options with regards to bringing in a new striker it's fair to say Conor was top of the list, our number one target actually, so we're delighted to announce his arrival.
"Having tracked him closely at Kilmarnock and, as everyone knows, being so close to bringing him in 18 months ago, we've monitored his progress at Wigan in the Premier League and we know he is capable of finding the back of the net.
"He is going to be a key player for us and when he plays regularly, we know he can score goals.
"We really like how hard he works too and that means he will fit into our squad comfortably."
