As much as I think United get a "fairer" deal of referees than we do, do we not think the reason they get more penalties and red cards for the opposition is that they attack with PACE! This means defenders dive in, give away penalties and run the risk of getting sent off! We, on the other hand, tippy tap the ball around at such a snail like pace that defenders have time to get back and don't have to take chances when tackling! Just a thought..............
