Lambert had been monitoring massive Czech attacker for some time now.
Aston Villa have completed the signing of giant Lazio front man Libor Kozak for an estimated fee of £7 million, according to reports in the Metro.
Head coach Paul Lambert has been keeping close tabs on the 6ft 4in Czech Republic international all summer long, with the Scot keen to add more strength in depth to his forward line at Villa Park this season.
However, the club were only able to finalise a deal for the 24-year-old on Monday evening as the clock slowly ticked down towards the closing of the close-season transfer window, much to the obvious delight of Lambert.
“We’ve been on this one for the last few months, trying to bring him to the club, so I’m delighted to get it across the line,” said Lambert.
“He’ll take that burden off Christian and he’ll add greatly to what we’ve got, with the likes of Nicklas Helenius, who’s a different type of player, Gabby Agonlahor, Aleks Tonev and Andi Weimann in that area of the pitch where we can hurt teams.”
Kozak, who put pen to paper on a four-year contract with the Midlands giants, had been with the Serie A outfit for the past five years, after originally arriving in the Italian outfit from Czech outfit Opava for a fee of just 1.2m euros in July 2008.
And in the intervening five-year period, the striker managed to find the back of the net on 22 occasions in 79 appearances in total in all competitions for Lazio, including 10 strikes in his 57 league outings for the club, with the four-times capped Czech forward saying of his move: “I’m really happy to be at Aston Villa and I’m ready for this new step in my career.
“I hope it’s a good step for me and also for Villa because everything is about the team. This is a big club, a very historic club with a fantastic fan base and, for me, this is really important.
“From when I was a young boy, I have dreamt of playing in the Premier League and to do this with a club such as Villa is incredibly motivating. It’s real now and I’m very happy about this.”
