The Slovakian international winger, who has spent the last four years at Eastlands without making a first team appearance, has signed a new deal that will keep him at the club until 2012.
"I have been here for four years now and I came here to realise my first team ambitions," he told the official City website.
"I am delighted to have signed this contract..
"I am excited about what the future holds and delighted that even with the players that City have got now, the club have given me the opportunity to progress and show that not only the big players can make it.
"The new deal shows that young players from the academy can progress. I am happy that I am one of them."
