There is every possibilities that Chelsea and Liverpool could turn around and make good qualifications from the group stage. I really believe Liverpool could do that more than Chelsea because Liverpool didn't sack their coach and their is no panic in the club, they could gradually find their way in.
But for Chelsea, Todd has created unnecessary panic in the club and it wouldn't be easy for a new manager to understand the team and begin to get results. He will definitely need some times to study and experiment, which could lead to more woes for the club.
But the two teams poor outing at the start of the Champions League shouldn't be a surprise to anyone because both teams are already finding a difficult time in the English Premier league. We shouldn't expect any magic, besides any club in the Champions League is a champion.
I can agree with you that Tuchel doesn't deserve the sack, atleast not at this time, because it is too early compared to his success in the club. The club though have changed administration seems to have forgotten too fast how Tuchel changed the team.
But what I will not agree with you is that Tuchel needed time to understand the NEW team. Was there really a new team? Nò. All the new players that joined the club were what Tuchel requested for. So, Chelsea bought him players of his choice and doesn't need a whole season to understand his new defence line.
In all I really thought that England will have an excellent champions league outing this year, but Liverpool and Chelsea are making me think otherwise after this first match.
