Kozak brought in to help Benteke - 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.

Libor has an unbelievable scoring record in the Europa League, incredible really.

He wasn't given much opportunity for Lazio in Serie A but he showed proper potential in leading the line there at a strong club with a great tradition and we need somebody like him as we only have Christian Benteke really as a main target man.
