Paul Lambert's move away from Norwich City is now all but certain after the club thanked him for his time at Carrow Road and said they 'fought hard' to keep him.
A statement from the club said: "The Club regrets to confirm that Paul Lambert has offered his resignation from his position as Norwich City Manager.
"We have fought hard to keep Paul at Norwich City and have not accepted his resignation whilst discussions with another club are taking place.
"However, whatever happens, we want to place on record our sincere gratitude for everything Paul has done for the Club over the last three fantastic seasons.
"When Paul joined us in August 2009 we were in 66thposition in the English football pyramid and the Club was on the brink of financial meltdown.
"Today we are a Barclays Premier League football club, on a financially sound footing and with a stadium full to capacity.
"Discussions with Paul throughout the last few days have been professional and amicable. Paul has already earned his place in Norwich City Football Club history and, no matter what happens, will always have a friendly welcome at Carrow Road.
"Meanwhile, contrary to some media speculation, the Club does not need to sell any players and the finances are in place to substantially strengthen the excellent squad which helped us finish in 12th position in the Premier League last season.
"Rest assured that everyone behind the scenes at Carrow Road remains absolutely focused on continuing to help the Club progress."
