There are performance clauses in his contract I would imagine. Otherwise he needs to fire his management team.
Norris is in great pain due to Mclaren's complete flop at the beginning of the new regulations cycle.. It has been obvious since Bahrain. He is competitive inside. He sees Verstappen and Russell (and even Daniel last year) winning and he can't stand it one bit. He believes he as a driver is on the same level as them. It must sting to be in the position he is now.
