The 32-year-old joined his hometown club on the transfer deadline day on a two year deal, but his main goal will be to secure a Premier League qualification for the Championship club.
"This is unreal, unbelievable! Imagine being a supporter and playing for the club you love. Words can’t even describe it. It’s just amazing, just a pleasure to be here," the winger said.
"They were my local side and going past the stadium when I was a youngster I thought one day I could play for this club. This is just surreal.
“All I can see right now is Bobby Zamora scoring at Wembley – I should be here talking about myself but that’s all I can think of right now!”
“It’s a very competitive league,” the Ghanaian continued."
“Every team wants to win promotion. I have managed it twice and it is a beautiful feeling."
“If I could get a third promotion that would be one of my great achievements. That’s my ambition.”
