Former Bolton striker Klasnic critically ill

Klasnic, a Bundesliga winner in 2004, now requires full-time treatment after a transplanted kidney he received failed.

The former Croatia international suffered kidney failure back in 2006 but recovered after receiving a successful kidney transplant from his father.

However, his latest transplant involved receiving a kidney from his mother, but his body rejected the kidney.

Klasnic now has to wait for deceased organ donors which in Germany, can take up to seven years.
