Throwing a game is a bit over the top but he picked a team that was not up to the task, similar to Leeds.I'm pretty sure Pep has never thrown a game in his life.
When he had the choice of bringing on 5 subs, he made 1 sub by choice. The DeBruyne substitution was forced upon him.
A 20 minute run out for Bernardo and Mahrez would have shown some form of urgency.
