Just because Crystal Palace can win against Liverpool does not mean that they are improving.
Sometimes teams have their own plans, and luck also plays a role. I think Liverpool played their best, but it wasn't their best performance. If they had played seriously, I'm sure they could have scored more. We can see how the final results each season in the EPL haven't been as impressive as Crystal Palace performance, but Liverpool have always been far better. So, I can probably attribute Crystal Palace victory to luck.
Well well I can't say it's all luck because Crystal Palace played a very good football and Liverpool as a team can attest to that, personally I feel Liverpool became a little bit relaxed and allowed Crystal Palace back in the game and before they realize it was all too late and again for the luck aspect I think I will attribute that to the game of penalties since they are no real masters of penalties and it's anyone games if it gets to that point.
We are not paying too much attention to Crystal palace enough. This guys won the FA cup and went silent like nothing happen only to come and kick Liverpool and won the community shield, we need to pay too much attention to what they can do this season in the Premier League and as well as Europa league. They are just moving like Tottenham, no too much attention but when they meet on the field, they shock everyone like it's their regular thing.
There is this changes that is coming to the Premier League and it's confusing to say what direction we are really heading next season. Liverpool won the last season and now they are playing like there is no enough confidence. I don't know if it's because they refused to resign their old players that left as free agent but there has been a replacement already. Their over all last season with crystal palace was fair but looks like they have lost that soft touch already.
