Liam Lawson endured another tough weekend at the Mexican Grand Prix. 

After narrowly missing marshals who were stood on the track, he was forced to retire on the opening lap following a collision with Williams driver Carlos Sainz.

This marks Lawson's 5th DNF of the season, and it comes as Red Bull are expected to make an announcement on their driver line-up next year.

Bob McMurray told Mike Hosking that all the junior drivers can do is wait for the announcement. 

'To be in, when Red Bull holds all the cards, they have your contract, you can't do anything else...it's got to be the worst situation for junior drivers.'
