Neil Lennon believes Leigh Griffiths has brought a refreshing change to Celtic recently.
The 30-year-old Hoops striker was out of the picture earlier in the season due to fitness issues which brought criticism from his manager in the summer.
However, Griffiths has worked his way back into contention and after coming off the bench to score in the William Hill Scottish Cup final win over Hearts at Hampden Park last weekend, which went all the way to penalties, he has started twice in a row for the first time this season.
The Scotland international followed up his goal in the 2-0 home victory over Ross County on Wednesday with another in the 3-0 Boxing Day win at Hamilton.
Lennon was happy with three goals in a week for Griffiths and he told Celtic's YouTube channel: "I thought he played very well.
"It was a great goal and I thought he could have had a hat-trick. He will be disappointed.
"But yes, he has been a breath of fresh air in the last few weeks.
"So it is (about) keeping him fit and keeping him at it."
French striker Odsonne Edouard netted a penalty just after the break and midfielder David Turnbull added a third goal after Griffiths had scored with a drive from inside the box to keep Celtic 16 points behind Rangers at the top of the Premiership with three games in hand.
The champions play Dundee United on Wednesday before travelling to Ibrox on January 2.
Lennon said: "We have a bit of work to do, we know that.
"We look forward to the Dundee United game and look to win that and take things from there. But I am delighted with the form we are in.
"I thought the two centre-halves (Nir Bitton and Kristoffer Ajer) were excellent, the two full-backs (Jeremie Frimpong and Greg Taylor) were great, the whole team functioned perfectly, the way we want them to."
Accies were without 10 players through either suspension, injury or Covid-19 issues but in dreadful conditions in Lanarkshire, they held the Hoops to a goalless first half before succumbing to their lively visitors.
Hamilton are one point clear of bottom side Ross County ahead of their trip to St Johnstone on Wednesday.
Boss Brian Rice was pleased with his makeshift side's performance against the Parkhead outfit and wants standards to remain high in Perth.
He told Hamilton TV: "I will expect more. I will demand more again.
"Hopefully we have one or two of the track and trace boys back (players who are self-isolating after being deemed a close contact of the team-mate who tested positive for Covid-19) but the injured boys won't be back.
"We will need to go to St Johnstone, hope to put in a performance and win the match.
"We gave it everything we had against Celtic. We were well-organised, disciplined and stuck to the game plan.
"I thought some of the performances were outstanding against a good Celtic team."
