Timo Werner and Kai Havertz cost Chelsea a combined fee of over £100m, and the pair seems to be struggling at the moment.
Werner started his Chelsea career with banging form, but has since been on a slump that has seen him unable to score in the last 14 league games.
For Kai Havertz, he has never really had it work for him since moving to the club from Bayer Leverkusen.
Chelsea defender Antonio Rudiger, who’s national teammates with Havertz and Werner, has hailed the quality of the duo and backed them to regain form.
According to Rudiger, living abroad for the first time could have stalled their development.
“Our relationship is good. I’ve known the guys for a long time, especially Timo. I already played with him in Stuttgart. But I already know Kai from the national team,” Rudiger told Sky Sport Germany.
“They are very talented guys, maybe in a little slump right now, but if you saw Timo’s performance against Sheffield United, then he was very important to us.
“He makes a lot of runs and I think the goals will come. That applies to both of them. This is their first experience abroad, they have only been in Germany so far, have only ever been in a safe environment, as I would call it.
“This is new territory for them and my job is to help them. I encourage them and I am just there for them.
“But at the end of the day they have to do their own work on the field.”
