That is true, Liverpool  have experience of blowing up leads, last year everyone saw them winning easily, hype was big, everyone was sure of it.

But i think situation this season is different. They don't have that  hype going on because of their history of blowing up leads and everyone  that City will be constant threat. On top of that you add  that win against Chelsea (imo Chelsea is much better than the current EPL table shows), where they didn't exactly dominate, but they managed to get win despite that. That shows me that team matured, and is getting winning mentality, and that is not something you can build overnight.
