Manchester United are stepping up interest in Leeds United defender Robin Koch.

Following Leeds' relegation, Koch is available this summer.

Kicker says United are pushing hard to close a deal for the stopper, who has a year to run on his current deal.

The 26 year-old, however, also is a target for West Ham and Bayer Leverkusen.

Koch, who won eight caps for Germany, made 39 competitive appearances for Leeds this season.
