The Bhoys will host Thistle at Celtic Park in the Scottish Premiership on Wednesday.
The Hoops are currently seven points clear at the top of the league table with a game in hand, while Alan Archibald’s side are ninth in the standings at the moment.
Celtic will be most Scottish football followers’ favourites to win the encounter, but Collins has underlined the reasons why they cannot be complacent.
“They are a good football team and lots of credit go to their manager for the way they try and play the game,” the 47-year-old told Celtic’s official website.
“They have been in the bottom half of the league most of the season, but they have still stuck to their principals and tried to play.
“We know they will try and get the ball and pass it but we are at home and we have to try and score that early goal and control the game.”
Thistle are a good footballing side and are in a decent position in the Scottish Premiership table, and indeed they could cause an upset at Celtic Park.
However, Celtic should feel confident of picking up all three points against the Jags, especially at home.
The Hoops are in a great run of form at the moment and will head into Wednesday’s contest on the back of a 2-0 victory over St. Mirren away from home at St. Mirren Park in Paisley.
