That tweet said it was the official Liverpool team bus that was blocked off on a side street and the tires were deflated. Imagine being a rival player and a large group of the rival fans stops your bus on a side street and deflates the tires? It's not good.
Luckily it seems like we misunderstood that tweet as the bus seems like it drove off so clearly the tires weren't deflated. But still.
1. It's the match itself which is being targeted.Trying to stop the Liverpool team from getting to the ground is targeting the team.
2. Who the feck cares?
