Robin Koch can leave Leeds United for NOTHING this summer, it has been revealed.

BILD says the Germany defender can leave on a free transfer thanks to a clause in his contract regarding relegation.

Manchester United are in talks with Koch about a move to Old Trafford.

However, a return to Germany is also being mooted, where Eintracht Frankfurt are keen on the 26 year-old.

Koch made 39 appearances for Leeds last season.
