The 26-year-old German international was recently linked with a move to Manchester United, and he says a switch to the English Premier League could not be a million miles off.
“In the end we should not forget that playing football is our job, so people should accept that wages will always play a role in a player's decision-making,” he told Welt am Sonntag.
“Of course, the wages that are being paid in the Premier League are very tempting. It would be hypocrisy to deny that.
"You have to look at the complete package to determine whether something is right for you. What's good for you one day will not necessarily still be good for you the day after.
"I know that a lot of German clubs are unhappy with the Premier League clubs' spending, but I think it is something good for all clubs in the end. It can only be a good thing for football when clubs invest so much money."
