Liverpool are certainly a tough team, the only one with full points.
Chelsea also have a good chance in my opinion.
Arsenal have potential but are unlucky and easily discouraged in my opinion.
I honestly see Manchester City out of the title race.
It's very okay for everyone to tip Liverpool to win the premier league this season. They have spent a lot of money and I think they have a good squad, but I really think Arsenal is a serious title contender and we should also understand that they have played tougher opponent than Liverpool. Liverpool has won their first 3 matches, but I don't think they have won convincingly in my own opinion.
Like I said Arsenal is a serious contender and I also see Chralsea staking a claim to the title. I really can say match about Manchester City, but with Pep's reputation, I would not like to write them off. I just think they need to solve their defensive issue and they will also be at the top.
I have not tip up Liverpool to win the premier league this season because the league just started and it is very obvious it hasn't balance even though some teams are tending to be good and outstanding. Liverpool got a lots of players so do arsenal and Chelsea and Manchester city also did and the fact that Liverpool won arsenal doesn't justify anything, it is football and nothing is new or changed. I think Arsenal will be playing Manchester city at the middle of this month and apparently people will carry or say arsenal will defeat Manchester city it may be possible though but I don't see it that way and that's my own perspective on the game.
