As you have mentioned you don't know much about 91. The reason for the explanation is that they are very arrogant and boast loudly about their machine team that " plays up ". They play 2026 B teams and boast about playing up , however they haven't come across the A teams ....and I'm sure they won't make that mistake again . You're right , playing up should be good for them , but you would need to hear them to really understand why someone would point that out .
