For Guanyu Zhou, his tenure at Sauber (Stake F1) is likely to come to an end after the current season. Audi - who now almost completely own Sauber - have a lot of drivers on the high as Nico Hulkenberg's potential teammate, but the Chinese is not among them. Zhou is mentioned at Alpine though, possibly because of the huge sponsorship amount ($30-35 million) he would bring with him to a new employer.
