They had god knows how many counters because we were down to 10 men and chasing the game to the extreme with just 1 or 2 men back at times. It's a completely different thing to simply play with a higher tempo and higher pressing game as we did last season.
And you were able to push up so much and put pressure on them because they were tired and you almost entirely ignored defending. You can't then point to the last 20 minutes and say "look, thats how we should have played the whole game"
Sturridge and Suarez were fantastic last season and killed teams off but they were able to because of our midfield. When we went on that winning run the likes of Henderson, Allen, Coutinho and Sterling were overrunning sides in midfield - it's gone now.
Its easier to overrun sides in midfield when they are so worried about your attackers getting in behind them. Teams will be more defence minded and not so expansive. They won't press too much for fear of being caught out and punished repeatedly. When you have a toothless attack why wouldn't a team push up into your midfield when they know that stifling that will kill your threat.
