St Mirren manager Danny Lennon knows Celtic will have a point to prove to their fans after a turbulent week - but he stressed his players were eager to make their own point in Sunday's meeting between the two.
Celtic visit St Mirren Park on the back of a home defeat by St Johnstone in the Clydesdale Bank Premier League and a disappointing Europa League loss to Sion. Celtic may yet win a reprieve and replace the Swiss side in the group stages if Sion are thrown out by UEFA amid a dispute over a transfer embargo, but the Parkhead team are under pressure to get back to winning ways.
Saints are also keen to put on a show after a promising start to the season during which they have produced an attractive and attacking brand of football, losing just once, to Motherwell, in the process.
Lennon said: "I certainly know, coming in the back of a poor week by Celtic's standards, Neil Lennon and his players will be looking to win the fans back over.
"They will be looking for that professional pride. Being an Old Firm player or manager brings its own special kind of pressure and they are only ever two or three games away from a crisis.
"We certainly know the qualities Celtic possess and they have good players, but we have good players and we will look forward to and prepare for the challenge we face."
