"I've always said I would love to end my career in England and that plan is still on track.

"Things are quite tough for Coventry City at the moment and I understand what is expected of me," he continued.
"I had the opportunity to train with the players here, I see great qualities and believe things can get better.
"I love scoring goals and helping my team-mates to score, together we can lift the club.
"I know this league very well because I have played in it with Leicester City and Reading in the past."
