Aston Villa striker Libor Kozak has insisted that there is more to come from him following his first goal for the club in last week's win at Norwich City.

Kozak said that he was pleased with the praise received by manager Paul Lambert, but said that he has not started to show what he is capable of.

"It's definitely a good start as it would have been worse if I had to wait [for my first goal]," Kozak told isport.blesk.cz. "It's fine that I scored but now it's even more important to build on that.

"Coach Lambert praised me after the match but I have to show a lot from my abilities yet. First of all I need to adapt myself because it's a lot different to Italy. I am far from my ideal form.

"But it's going to take some time yet, though I have a good feeling."

Kozak joined Villa on transfer deadline day.
