Meyer has four days to correct team problems

If I were a Ref, I would send players off for dissent for all this ridiculous gesticulating and playing for penalties. It also does your team no favours whatsoever.

Like someone composing articles or threads about a players strengths post match, when said player has been very poor.....

 Ah the simple rush defence as basic and as old as the hills
