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.
