Haas drivers Kevin Magnussen and Romain Grosjean have been exchanging compliments ahead of the new season.
Toward the end of the 2017 campaign, Grosjean said that Magnussen was the "best team-mate" he has ever had and the two drivers will spend a second season together after the American outfit opted to trigger one-year extensions.
After learning of what Grosjean said about him, Magnussen was more than happy to heap praise on him in return.
"I appreciate the compliment," Magnussen said via Auto Hebdo. "Romain is also a very strong driver.
"I would even say he is unique as I have never seen someone who can overcome the blows in the way that he can."
Grosjean has had continuous struggles with the Haas car as it has been plagued by brake problems in recent years, but Magnussen has still be able to learn valuable lessons from him.
He added: "It's amazing how he can put together the pieces of the puzzle which is frustrating at times but I learned a lot from him last year."
Both Grosjean and Magnussen are out of contract at the end of the 2018 season, but there is an option once again to extend their deals by another year.
