Celtic rarely tear the lower half sides apart in the cup and I think they only beat Partick Thistle 2-1 this season in the last round, they beat Airdrie and Greenock both 3-0 last season and the season before that and I think it often gets the job done approach and get to the next round. These sides aim is to not take a tanking and keep it respectable, they will defend in numbers and enjoy their day of playing the old firm, the weather should help and I think Under 4.25 goals is a bet at current odds.
