Even after twenty games, fans cannot rely on their performance because, last season, they appeared to have already won the league; it wasn't until the final six matches that they dropped some significant points, causing them to lose the title. It was reasonable that there was lack of experience and tiredness, but they have enough squads this season that can weather the burden.
Arsenal took everyone by suprise last season with their brilliant performance and everyone felt they were already the title holders, i even had a bet with my younger one that they'll win the league but was very disappointed when they started dropping points in six matches to the end of the league, and allowed City to gap them and win the title again, it pained me cause I really bragged about Arsenal winning the league last season and lost a bet to my younger one.
Therefore this season I've learnt my lesson and I'm not going to decide any winner yet until its the last day of the tournament,no matter how good the team is playing cause I don't want to be disappointed like I was the previous season, we'll Arsenal's performance is good and they're one of the top contenders of this season.
