I think it will be too early to judge Chelsea. The season is just getting started, and they have a new coach, so they need to get used to his method first before we see their true colour for the season and whether they will do well or not. Their last game was against Manchester City, and we all know how strong Manchester City is.
We know that they are far better than Chelsea in everything, so I think we should wait and see how Chelsea will play their matches. Then maybe we can judge from their performance in their upcoming matches, but as of now, it's too early to say they won’t get tickets to the Champions League. Let’s observe Chelsea first.
It is too early to judge Maresca and Chelsea and with player resource they have, they can improve performances in coming months. Expand to Bundesliga, Xabi Alonso joined Bayer Leverkusen when the club was in crisis but he improved them in last two seasons. Maresca can do the same in Chelsea and we need to give him more time. Like last season, Pochettino received a lot of critics but at the end of season, he created a lot of hope for Chelsea fans. Unfortunately he was fired and now Chelsea will have to hope that a new coach, Maresca can bring them to success in this season and maybe in more future seasons.
