"He makes good use of his height and utilizes crosses from the wings effectively. He will continue to score goals with the help of players who are compatible with him," Perekli said, via Haber TS.
"Being the top scorer needs to be crowned with a championship title. Otherwise, it remains an individual achievement. I think he will score in this match."
