rA, you assume that the substitution was being made for injury (alleged injury) but how do we know that Sari was not wanting to bring on Caballero for penalties? After all he has a great record at stopping penalties in Wembley finals and is a former Mank City player so would know the habits of their penalty takers. Its not unprecedented to bring on a specialist penalty stopper in the last minute or so for that very purpose, I think Ive seen it done twice?

I assume that the substitution cannot be made after the full time whistle has been blown {MA?}, so (if this was Sari's motivation behind the decision) I think its not a manager having an unreasonable hissy fit at all, but a manager being undermined by a precious player, not unusual in the PL and indeed at Chelsea.....
