After the time we finished second in the league the tactics failed because most teams in the Premiership knew how to play against them. Houllier didn't have any other way style of play other than to tacticize around Michael Owen.
That's where the difference lies. Benitez on the other hand can change things around. He doesn't have the same tactics in every game and the way we play is a combination of various things. Whether it be passing our way forward, counter-attacking or going via aierial balls.
Houllier played two up front because Michael Owen needed a striker alongside with him who could feed him the balls [Heskey] thats why he played with two up front.
You can have an attacking team with the 4-5-1 formation and you can have a defensive team with a 4-4-2 formation, it all depends on the personal in the squad.
The first paragraph is complete


Also Michael Owen didn't "need" anyone along side him.
The rest of the post is perfectly valid.
