Haas F1 Team owner Gene Haas says he will not force driver Romain Grosjean to stay at the new American outfit if a top team wants to sign him.

A tough weekend in China -- where he finished 19th -- aside, Frenchman Grosjean has been impressive for the Ferrari-linked outfit so far, amid his obvious desire to one day switch to the works team.

Ferrari has a potential vacancy for 2017 and team founder Haas said, "I would never hold on to a reluctant driver. Romain is happy now, but if one of the two top teams (Mercedes or Ferrari) offered him a contract and was ready to pay the termination clause, it would be silly not to accept it," the Californian is quoted as saying by Italian media outlet Tuttosport.

"Romain is a good guy, and if he gets the chance to fight for the title it would not be fair if he was not able to try," Haas said.
