Middlesbrough boss Gareth Southgate admits he may have to sell Aston Villa and Fulham target Robert Huth.
"I would rather not sell him but I know there are certain things we have to do as a football club," the manager told the club's official website.
"Robert's approach is first class. Of course it would be fantastic if he could go to the World Cup with Germany and a move might help him to do that.
"But he has been very realistic about it and has told me he understands that for him to leave a club has to offer the type of money Middlesbrough want."
