The 21-year-old was particularly outstanding in the victories against Australia and England and is expected to play a key role in Saturday's quarter-final clash with Argentina.
However, Ozil has just a year left on his current contract with Werder Bremen and the Bundesliga side may opt to capitalise on his excellent form in the tournament by selling him this summer.
Ozil would not be unhappy about that prospect, saying: "The World Cup is all that matters at the moment but when I get back we can think about my future. For now it's not something I want to give a lot of thought to.
"To the top players the Premier League is attractive. You look at what Manchester United and Chelsea have achieved over the last five years and you see it would be easy to be successful at two clubs like that.
"I see what Michael Ballack achieved at Chelsea and the quality of players he played with and the temptation becomes obvious.
"Trophies are what matters to me. There are two teams in England always at the top and of course that's attractive. But the same is true for La Liga. They're the strongest leagues in the world."
Ozil has scored 13 goals in 95 appearances for Werder since making his debut for the club in February 2008.
