From next season, reforms mean the top four clubs in Europe will have four guaranteed places in the competition's group stage.

With 16 slots already taken, plus a further place for the winner of the Europa League, the chances for smaller leagues to get teams into Europe's biggest club competition will decrease.

And Ozil said: "Smaller teams must always have the opportunity to lock horns with the big ones.

"It has to be important in the future that every nation can bring a club into the Champions League and through that gets the chance to see world stars [in their country].

"The top teams should not build a closed shop in the Champions League."

He said he did not believe there was any need for a breakaway league or a Super League, adding: "If you change too many things, it would harm football. It's good as it is right now."
