Mowbray said: "Bartosz is a player we invited over to train with us after having him watched live. I believe he will add to the fierce competition we've got up front and offer us different qualities to the strikers we already have on board. He likes to get into the penalty area and get on the end of things in and around the six-yard box. Bartosz isn't the type of striker who's necessarily going to lift supporters out of their seat with dazzling skills. but he brings other attributes. He is strong, brave, can hold the ball up and gets into the box."
