Kristoffer Ajer was sent off for Hatem Abd Elhamed during Saturday afternoon's thrilling match. Now, Celtic boss Neil Lennon gives a worrying update. Celtic handedly defeated St. Mirren 5-0 while riding the performances of Odsonne Edouard, Callum McGregor and of course, Leigh Griffiths. After a disappointing spell of matches, the Hoops got it going again against the Saints. The much needed win puts Celtic 16 points ahead of Rangers in the table, but the cross-town rivals will have a chance to cut that lead down tomorrow when they take on Ross County. Furthermore, this win helps build momentum for the Hoops. With Rangers lurking next Sunday, they needed this type of performance. However, not all was well and good during Saturday afternoon's match.
