Al-Habsi told Sky Sports News, "Last season I came here in the middle of the season and it was difficult for me to have a position in the team. This season everyone starts at the same level."
"It will be a big challenge of course and I know in my mind that I have to work hard to get the position.
"This challenge is one of the most important in my professional life but I think I am ready for it.
"I had a fantastic holiday with my family in Oman so I come here with my mind clean just for football and like I said, I'm ready for it."
