Former Arsenal forward Eduardo is not ruling out a return to the Premier League in the future.
Eduardo, 29, left Arsenal for Shakhtar Donetsk in 2010 for £6 million having failed to make a significant impact in England after a horrific leg break in 2008 hampered his career.
Despite his struggles in the Premier League, the Croatia international would consider a comeback, although at present he is happy at Shakhtar.
"I am happy here at the moment," Eduardo told Globo Esporte. "I honestly don't know what will happen in the future. It is possible that I could go back (to the Premier League) one day.
"Football is very different in the Premier League, but the stadiums and the fans are fantastic."
Eduardo is currently preparing to compete at Euro 2012 with Croatia, with the nation facing a tough task to reach the knockout phase following a tough draw in Group C.
"The favourites to win the European Championship are Spain, Netherlands and Germany but there is always a surprise team and hopefully it will be us," he said.
"Our schedule is exactly what we want it to be. We open against Spain and finish against Ireland.
"I think we can qualify with four points. A win against Ireland and a draw against Italy will be important. The match against Italy will be the decisive game."
