The Reds have been excellent since January, climbing from 12th in the table, four points off the relegation places, with a goal difference of -1 to fifth place and a goal difference of +18.
The huge turnaround in form under Dalglish's reign as caretaker manager meant the decision to give him the job full time was an easy one agrees Ayre.
"It was an easy decision in the sense that there was never any other candidate. Over the last few months everybody has had a great opportunity to work together; the owners, Kenny, Damien and myself and it's there to be seen what Kenny and Steve Clarke have achieved together," said the club's Managing Director.
"When those things happen it's then about finding the right solution in terms of an agreement. We said from the outset that those things are private and personal and that's how we've dealt with it. We now find ourselves here with everything agreed and everything in place. There was never anybody else in the running.
"I'm not surprised by what he has achieved. It's an amazing achievement for him to have got us where we are but somebody who I respect a lot in football said to me once that if you are going to pick a manager then pick a winner. That's what Kenny is.
"For a long time we have needed people here who really understand what this club is and what it means to our fans and what makes it different to other clubs. Kenny knows that inside out and I think that's a key quality. He understands what matters at Liverpool and what needs to be done at Liverpool.
"I think humility is another great skill that Kenny brings. He has nothing to prove to anyone in football other than himself, but at the same time he treats everybody with the same level of respect whether it's somebody at the top or somebody at the bottom of the business. He treats everyone the same. I think you see that when you look at how he engages with players in different ways on and off the pitch, the way he engages with the fans, he just has great humility and at a football club like Liverpool that is a key strength."
