There is an argument that Kieran Tierney should have been operated on earlier in the season, when the extent of his injury became clear, but if he is fit to start against Hearts on Saturday, he should play. A few days delay to his op and convalescence will make little difference.
The same is not true of Mikael Lustig. Mikael has been injured four times since November and is clearly in a fragile state. Starting him on Saturday risks a repeat of a scene we have become familiar with: Mikael hobbling off early in a game and curtailing the manager’s tactical options.
Jeremy Toljan and Anthony Ralston can both deputise at Hampden, one of whom should start. Neither Mikael or Neil Lennon will know for sure if the full back will remain at Celtic after the Cup Final, but thoughts of an on-field farewell should be kept until after the game is won.
