Hamilton revealed before qualifying that he was ill and almost decided to not take part and offer his
Mercedes seat to Esteban Ocon for the race.
The Brit ended up qualifying on pole despite the illness but a poor performance in the race left him finishing outside the points but ended up finishing ninth after the Alfa Romeos were penalised.
Hamilton went off at the penultimate corner and damaged his front wing. He then came back onto the track and cut across the grass into the pitlane, which led to a five-second time penalty.
