The current Liverpool team isn't as strong as that of the previous season. It's obvious that they have conceded a total of 4 goals making it a strong possibility that Arsenal can still score them in Anfield. Since the both teams are strong,home advantage wouldn't count much to determine the winner of this game. It would also be difficult for Liverpool to concede defeat in Anfield and Arsenal wouldn't want to lose the game either. My own prediction of this match between Liverpool vs Arsenal is Draw. This game will end as a draw and with Both sides scoring each other.
And even when Liverpool won the league, they were just lucky because not all the clubs were doing well. The thing now is that every club has improved, and we are going to know if Liverpool is really good or not. To me, they were just lucky. And even Arsenal is on the same level, but we should not underestimate them because when it happens, we will not be able to predict who is going to win. Arsenal is starting the season well, and their blood is still hot, maybe because the season is just starting.
And if Arsenal cannot in anything this season, then they need to do something about their coach because his not fit for that job, and some people are ready to do better than him. And the game between the two of them is going to be a tough one.
