Bebe blames injury on his career stalling.
He said: "I'll give it everything while I'm here and try to help the team to continue occupying the places that they have been in the table.
"Obviously something went wrong in the last phase of my career, I had a serious injury which thankfully I have fully recovered well from.
"I'm fine physically - I was always training and playing. It's good to come here and I want to show what I can do."
