"If you look at where he came from with Lisbon, he played in a fairly young side, so for someone of Ricky's age to show that responsibility and those leadership qualities it shows he can be a focal point," he told the Pink 'Un.
"Especially when you are a main striker in the team as he was there. They were reliant on the goals that he scored, but it was a wonderful record in the time he was there, and he proved he could adapt from his early days in Holland.
"That is what excites me and is why we are all looking forward to seeing him out there on the pitch.
"I don't believe with how tactical and with the sheer speed of the game nowadays that you can just be a goal scorer. First and foremost you have to a team player. His performances have shown a real good indication of that.
"He wants to get in the box, he is somebody who wants to get forward, but in that lone role he can play it and with that comes a real responsibility."
