Haha, so there are still people who compare the new season to the preseason games? Wake up, guys. The Chelsea team is much better than Arsenal and Tottenham. They competed for the league title last season until January, when they lost steam due to COVID19, and they finished the campaign as semifinalists in the Champions League and winners of two domestic cups runner-up medal. Chelsea is a force to be reckoned with; they want the league this season.
I agree with your opinion about Chelsea. They are one of the most serious contenders of the Premier League title at the moment. It wouldn't be the right thing to overlook them this season. I can still say that they need some transfers now on one hand. For example their biggest need is a striker now as Lukaku is no more here and Werner might also leave the team soon. If they somehow find the right striker for themselves then they would really compete harder to achieve the title.
I can't argue about them not being pretenders, but nevertheless - there are at least two of the biggest rivals, Liverpool and Manchester City, who will definitely be competing for first place again next season. I for one don't see Chelsea in that competition, they're a bit out of step with those teams. But they will be fighting for the top four one hundred per cent
