Yeah, Man Utd have always been the benchmark for a quick tempo game, agree that Monday they looked a lot sharper and quicker last season, probably down to the much younger team. I find that the most entertaining type of football to watch personally. It's why I loved us so much under Bobby, played a high pace game similar to Man Utd.
I think in general a lot of English teams play a higher tempo atm, though last season the top sides were the worst they've been for a while imo. Spurs for example play high tempo too. It doesn't mean a higher tempo is any better in any way, I think that's where there's an issue in the debate, it's just an observation, look at Blackpool last season who played too quickly and got caught out because of it.
