Liverpool legend Dalglish was sacked by the club's American owners in May last year and replaced by Brendan Rodgers after the Reds finished eighth in the Premier League.
The Reds had picked up their first trophy in six years in 2012 when they won the Carling Cup and also reached the FA Cup final, but that was not enough to save Dalglish's job.
The Scot has defended his record in that campaign, and believes winning a trophy and reaching another final was more memorable than finishing fourth and qualifying for the UEFA Champions League.
"What those boys achieved in 2012 was fantastic. To win the Carling Cup and to get to an FA Cup final was beyond any expectations," Dalglish said in his book 'Kenny Dalglish My Life' serialised in the Daily Mirror.
"Liverpool is a massive football club and they had not won anything for six years when I got there, but we won something in our first season.
"People will turn around and say we finished eighth in the league, but how many points would you swap for three Wembley trips? That League Cup was a trophy for Liverpool Football Club. I don't see that as anything but a positive. It's always pleasant to get a winner's medal.
"It might be more rewarding to qualify in Europe after finishing fourth, but who remembers that game when you finished fourth to get there? Winning a Cup final against Cardiff at Wembley and walking away with the Carling Cup was a day to remember.
"Yes, I would have loved to have finished fourth and I would have loved to have won the Champions League and won the Premier League, but it was never going to be achieved overnight."
Although he was hurt by his sacking, Dalglish, who was a club ambassador before returning as manager, has confirmed he would return to the club if asked to help out.
"I've always said that I'm happy to help Liverpool Football Club in whatever way I can and that hasn't changed in any way, shape or form," concluded Dalglish.
