He achieved that ambition but only two games into the new campaign it was obvious he wasn't going to be first choice and he's made the move back to the Championship with the ambition of taking Cardiff City to the top level.
He told the official website http://www.cardiffcityfc.co.uk
"It's a great club with lots of ambition. I hope that I can help with that by scoring goals for Cardiff City this season, with the aim to get the club to the Premier League.
"The manager is playing football the way that I want to play, and he knows what I'm looking for as a striker. I'm looking forward to working with him and his coaching staff, along with my new team-mates here, a squad which is shaping up very well.
"I moved to West Ham with the hope of playing in the Premier League regularly, but that wasn't to be. Knowing that my chances would be limited there at Upton Park, it was down to me to find a club where I knew I'd be happy to play. It's my aim to play week in week out, which I hope to achieve by playing well for Cardiff City. If I'm scoring goals I'm happy, which I'll enjoy doing in a Cardiff shirt.
"I'll be meeting my new team-mates on Saturday, getting straight to work on the training pitches here ahead of the task of trying to secure three points in our home game against Wolves on Sunday."
