The Hoops beat Inverness Caledonian Thistle 4-1 at Celtic Park to be crowned Scottish champions for the second consecutive season.
The manager told the club's official website: "There is a feeling of pride and happiness, along with real joy for the players, the club and the supporters. It's always a momentous feeling and occasion when it comes round, and it's a tremendous effort by everyone.
"It's your remit and priority at the start of the season, and obviously with the Champions League run and getting to the cup final, it all just adds up to what's been a fantastic, memorable season for us.
"There have been times where we have been a little inconsistent, predominately after the Champions League games, and that's something we need to improve on going into next year as you are always looking to improve and progress the team. So the experience from that will stand us in good stead if we qualify again."
Celtic will play Hibernian in the final of the Scottish Cup next month.
