Derby County have confirmed the signing of Matej Vydra from Watford for an undisclosed fee.
The 24-year-old has signed a four-year deal with the Rams, committing his future to the club until 2020.
The Czech Republic international has spent much of his career in the Championship, including a loan spell with Reading last season where he scored nine goals in 36 appearances.
"We're really pleased to sign Matej Vydra – we hope that he will bring goals and energy to the team. His ability to exploit space with his pace is good and something that we need, while his goals record is pretty healthy as well," manager Nigel Pearson told the club's official website.
"I hope that another fresh face will provide a lift to the dressing room. Without wanting to pile any pressure on him, coming into a new challenge here at Derby County, we hope that he can be the catalyst for us to start bringing some more positive results, which are obviously something that we need.
"We've brought James Wilson in as well from Manchester United recently and we hope that the two of them will give us different options up front and help us, as a team, to win more games."
Vydra becomes Derby's second signing of the summer after Wilson.
