It didn’t take long for McLaren to find a ready and willing substitute for Fernando Alonso, after revealing this week that the Spaniard would be missing the Monaco Grand Prix in favour of racing a McLaren car in the Indy 500. The team are bringing back Jenson Button, who retired at the end of the 2016 season as a full time F1 racer, to become the reserve driver this year and focus on other interests.
