Bok captain Kolisi helps get Red Bull up to speed for Monaco GP

The Monaco Grand Prix is the jewel in the Formula crown, attracting not only the best racing drivers but also celebrities and sports people from other codes to the principality's streets.

One of those was Springbok skipper Siya Kolisi, who not only watched the action unfold on the first day of practice but was also roped in by Red Bull as part of their pit crew.

The two-time World Cup winner took to Instagram on Friday afternoon to show his contribution in helping the team who have dominated the season so far.

"No, I am not ready," Kolisi joked when asked if he could help with a quick tyre change on one of the Red Bull RB20s.

Kolisi did, however, help push start one of the cars before the experienced Red Bull crew, who regularly change tyres during a Grand Prix in under two seconds, went to work.

Despite Kolisi's help, Red Bull didn't have the best of days. 

They finished off the pace in both the first and second practice sessions, as Mercedes (Lewis Hamilton) and Ferrari (Charles Leclerc) led the timing boards.
