Kai Havertz lifts lid on the work Graham Potter has been doing behind the scenes at Chelsea

Chelsea forward Kai Havertz says the squad is gradually taking to new manager Graham Potter who was appointed days after the sacking of Thomas Tuchel.

The Chelsea squad looked like they had been surprised by the decision to sack Thomas Tuchel who masterminded their Champions League success against Manchester City in Porto.

Under the German’s guidance they also won the UEFA Super Cup before adding the Club World Cup trophy trophy to their cabinet.

He was also in charge as the club went through sanctions and brought in players to replace the departed Antonio Rudiger and Andreas Christensen after both played a key role, but left for Real Madrid and Barcelona respectively.

His sacking just six games into the Premier League season followed a disappointing 1-0 loss to Dinamo Zagreb in the Champions League.

But striker Kai Havertz says the team is getting used to the new man and there is belief within the squad that they will go on to have a good season.

He told Kicker in Germany: “Our new coach has made a very good impression, we have a great squad.

“I think we are in for a good time.”

Some fans have questioned the appointment of English manager Graham Potter, citing his lack of experience in managing world class players as a big blow in a dressing room like Chelsea.

But to his credit, he managed Ostersund, a small Swedish club, and took them from the fourth division to the Europa League, recording wins against the likes of Arsenal and Galatasaray on their way.

He’s also transformed the football at Brighton and Hove Albion, and led them to an impressive ninth place, their highest in the history of top flight football.
