At least it has been an entertaining win for the fans who have pinned a lot of hope on Pochettino so far. Brighton is a good team to provide the best resistance against Chelsea, but Chelsea managed to overcome the challenge even though they could only score 1 goal.
That victory made Chelsea and Pochettino breath deeply. I think if Chelsea lost it and got kicked from EFL Cup then it will be a yellow card for Pochettino and just another bad failure will send him out of the club.
Hopefully this victory could make the team more stable and trusting themselves. In the other hand I feel sorry for Brighton, they deserve to play in further stages but that's all for them.
