Kai Havertz saw signs on Saturday of an increasing coherence and confidence among the Chelsea players, something the German believes will only improve as the squad’s fitness continues to build up.

In these unusual times a proper pre-season was not possible, meaning Havertz was among the players whose very first game in a Chelsea shirt was a competitive one. His performances have improved game by game since that debut at Brighton, with the weekend victory over Crystal Palace offering further proof of collective progress.

‘The first half was difficult because they were stuck in their own half and it was difficult to create chances, but the second half was better,’ said Havertz.

‘We played well and scored four goals. It gives us a lot of confidence. After the international break we have to continue like this.

‘It takes a bit of time to find connections. A lot of players, like me, didn’t have pre-seasons, and a lot of players are new. It takes maybe a month for everyone to settle in nice. It’s different for players to come from another country, young as well, but now we are settled in very good.

‘We are getting more comfortable on the pitch. We all have to get a little bit fitter and when we do that we will play better and better.

‘We can achieve a lot this season. We have very good players, a good coach, and we are here to win titles. That’s our goal.’

Four games into his Premier League career, Havertz is also better placed to judge the contrast between the English top flight and the league he had hitherto plied his trade in, the Bundesliga.

‘It’s very different to Germany and that’s a reason some players need a bit of time to adapt,’ he noted.

‘There’s a lot of running in the Premier League, very aggressive. In the Bundesliga when you play against lower-placed teams sometimes it’s easier, but here when you play against teams like West Brom or Brighton they can play very good football.’
