Lol it's weird to have to fire a coach before the season starts, what can we expect when a new coach just wants to build a squad it would be better to give it some time and see how it improves. Chelsea have a coach with experience in the Premier League so there is no need to be too quick to say anything in a friendly match like this we don't know what potential is hidden. What is clear is that when management decides to choose a new coach, he deserves to be given a chance at least until the middle of the season..
I don't understand whether it's just a rumor or what and this is just a friendly match and maybe we can see a strong team can lose to a weak team. Every coach definitely needs to adapt, especially in the Premier League where the competition is much tighter and it's not easy for a new coach to provide quick success there. Pep Guardiola also needed time to build Man City into a strong team and maybe Chelsea should see this pattern if they want to achieve success.
Firing a coach for the wrong reasons doesn't provide a solution and what the coach needs is trust and they are given time to build the team. The Premier League is different and I'm sure it's not easy to come here and be able to provide success in a fairly short time because the coach needs to adapt to the players and the style of play in the Premier League.
