Celtic manager Ange Postecoglou says Lanarkshire duo Anthony Ralston and Stephen Welsh are key to his plans - even if they aren't playing.
The right-back and central defender weren't picked to start in last Saturday's convincing 7-0 Premiership win over St Johnstone, as they maintained their six-point lead in first place with five games to go.
Postecoglou's men face Rangers in a huge Scottish Cup semi-final this weekend and every player will be key if they are to achieve success.
