"I have given everything to Celtic as a player and manager already in my career and I am ready to do the same again".

Kolo Toure and assistant Chris Davies are also poised to join Rodgers at the King Power Stadium.

Kelly has denied the charges and maintained his innocence. "If your friend was in trouble, wouldn't you bail them out?" she said. Among the conditions of Kelly's release is that the 52-year-old artist have no contact with females younger than 18.
Former manager Neil Lennon is expected to take over at Celtic Park on an interim basis.
'Given the bulk of the club's income falls into the first six months of any season, the board is satisfied that the results for the full year will be good.' Rangers will hope to draw additional financial benefits from domestic success this season, with the Scottish Cup being their best chance of a first major trophy in eight years.
Asked if he is surprised by the timing of Rodgers' impending departure, the Rangers boss said in a press conference: "Not really, because these things happen".
But ex-Hoops striker Hartson believes Rodgers will be staying put, at least while winning 10 Scottish titles in a row is still possible.
"It seems (the lure of Premier League has been a big factor) otherwise he'd have declined the opportunity to talk to Leicester", the ex-Premier League star was quoted as saying by Sky Sports.
It's Leicester City, though, who have successfully managed to lure Rodgers back to the Premier League.
