Matej Vydra has joined Derby County from Watford in what Sky sources understand to be an £8million deal.
Vydra enjoyed two loan spells at Vicarage Road before penning a permanent five-year contract with the Hornets last summer.
However, he went on to make just one further appearance before being shipped out on loan to Reading, scoring three times in a 31-game spell at the Royals.
The Czech Republic born attacker has this evening penned a four-year contract with the Rams, much to the delight of manager Nigel Pearson.
He said: “We’re really pleased to sign Matěj 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.”
