After failing to seal a deal for young Oman keeper Ali Al-Habsi, who had impressed on trial from Norweigan club Lyn, speculation has suggested Bolton's Finnish international is now in the frame.
28-year-old Jaaskelainen has been one of the most consistent keepers in the Premiership during his 6 year spell with the Wanderers.
However, Bolton boss, Sam Allardyce, has denied all knowledge of any approach and, tongue-in-cheek, suggested that City couldn't afford him anyway.
"I'm sure if City were interested in Jussi they would have already contacted us," he told Sky Sports News.
"Obviously, with their goalkeeping problems, they would be interested in signing a keeper but I don't think Man City have got that much money left, have they?"
