Manchester United target Edmond Tapsoba has suffered a serious injury.
The 22-year-old defender is set to miss the beginning of the Bundesliga season with his team Bayer Leverkusen.
Tapsoba has been a key target for United, Chelsea and Arsenal this summer.
Respected Sport1 journalist Patrick Berger has reported that Tapsoba suffered a serious ankle injury that will derail his preseason preparations for the new season.
Leverkusen are willing to sell the defender, but want a fee in the region of €60 to €70 million.
