ANGE POSTECOGLOU insists Celtic must be better next year as he discussed a possible second season improvement theory offered by fans of his previous clubs.

The Parkhead boss has all but mathematically lead Celtic to the Scottish Premiership title having already won the Premier Sports Cup in his first season in Glasgow.

Postecoglou - who was voted Scottish Football Writers' Association Manager of the Year -

is said to enjoy a huge improvement in his sides after a full year of working with them to implement his footballing ethos.

Regardless of the theory, shared by fans in Japan and Australia alike, Postecoglou is firm in his belief Celtic must be better next season.

Speaking at the SFWA awards dinner, he said: "Look, we have to be better next year, irrespective of how we went this year.

"But the way I want teams to play and the whole training process and everything – it takes a while for people to gel to.

"I'm really hopeful that next year we will be a stronger team. We have to be, and I look forward to what that brings."

And quizzed on his feeling after winning the Manager of the Year gong, he added: "I'm very proud and humbled to receive the award, there have been a number of outstanding performances by managers this year.

"I'm pleased and humbled to receive it but I also acknowledge I've had tremendous support, particularly from the staff and everyone at the football club. And obviously, the players have been outstanding."
