Gabriel Agbonlahor has showered teammate Libor Kozak with praise for his contribution to Aston Villa since joining the club in the summer transfer market from Lazio.<br /><br />&ldquo;It must have been difficult coming in knowing he has to compete with Christian - one of the best strikers in the world.<br /><br />&ldquo;He has come in, scored and has been a handful. He battles on during games and he got his reward for working hard. <br /><br />&ldquo;He is quiet and keeps himself to himself but he enjoys his football,&rdquo; Agbonlahor told the Birmingham Mail.<br /><br />Libor Kozak, 24, signed a four - year deal with Aston Villa on September 2 and has gone on to net two goals in the Premier League.<br /><br />Photo Credit : lucrativesport.wordpress.com <br />
