Neil Lennon feels Leigh Griffiths still has "a bit to do" before he hits peak form.
The forward netted a brilliant hat-trick in the convincing 5-0 victory over St Mirren at Celtic Park – a win which takes the league leaders 16-points clear at the top.
However, while delighted with his impact, Lennon reckons there's even more to come from the 29-year-old.
He told BBC Scotland: "He's got a bit to do.
"But that's far more like him. He's been working hard ever since the beginning of the year, I don't know how many goals he's got now, maybe that's him up to 11 which is a great return considering he hasn't played that much.
"We know what we've got with him. I'm just pleased for him on a personal level. He's come a long, long way and that will mean a lot to him today.
"It's fantastic, another fantastic day for us. Clean sheet and five great goals to top off what was a very efficient performance from us today."
