Millwall have pulled the plug on a deal for Ipswich Town goalkeeper Bartosz Bialkowski at the eleventh hour.
The 31-year-old underwent a medical with the Lions last Thursday after the two sides agreed a fee of £900,000 for the Poland international.
According to the East Anglian Daily Times, the medical flagged up an issue with Bialkowski's knee, prompting Millwall to attempt to renegotiate the transfer fee.
After some discussions, Town - relegated to League One for the next campaign - decided that they could not accept a substantial reduction in the fee for a player who was valued at almost £4m a year ago.
"We agreed a substantial fee with Ipswich for Bart. He was in my office, paperwork was signed and agreed, terms were agreed with the player," Millwall manager Neil Harris told reporters. "He's a fantastic character, real nice lad. Everything was okay with Ipswich, but there was a complication with the medical, which has led to complications with the deal. As we stand at the moment the deal is off."
Ipswich boss Paul Lambert added: "You only move if the club lets you move. The club has got the hold. Bart has been great. I had a chat with him yesterday and he was really fine, no problem. He's really focussed and is our player and will continue to do his best for the football club."
Birmingham City are also thought to have expressed interest in signing Bialkowski, who has two years left on his current deal at Portman Road.
