While Stroll was handed a 5s time penalty after the stewards determined that he "made contact with Alonso and forced him off the track", the Spaniard was similarly penalised, the stewards deeming that "although Alonso was forced off the track, he thereafter cut the chicane and rejoined the track thereby gaining a significant advantage". He is now competing in the World Endurance Championship alongside his F1 commitments this season, but the IndyCar series remains an option as he looks to become just the second driver ever to win the Monaco Grand Prix, Le Mans 24 Hours and Indianapolis 500.
As the pair approached the final chicane on lap one, Stroll pushed Alonso onto the grass, with the Spaniard then driving across the gravel to rejoin the circuit instead of using the escape road. He is keen to take on a new challenge, one which will allow him to compete again for race wins and world championships. He later apologised to Alonso. "This is how bad Formula One is".
"It's hard to understand the decision but you know, this is how bad Formula 1 is", said Alonso. You are braking on the outside at the last corner and you go on the gravel, you come here to apologise and you get a penalty.
McLaren's Sporting Director believes if Alonso wasn't caught up in the incident with Stroll, then he would have secured a much better position for his team. He didn't see me, because if he did, he wouldn't have pushed me on the grass.
Stoffel had a hard first stint on his initial set of tyres, but by the final stages of the race was rapidly closing on the pack of four cars ahead, although he ran out of laps to be able to make a move stick.
"Unfortunately, the five-second penalty I received in the first part of the race dropped me down several positions". In the last couple of laps there was also a good battle with the Williams and [Marcus] Ericsson who were struggling on old tyres, so we had to fight a little bit.
"I just wanted to say no hard feelings over the first lap", Stroll said of his conversation with Alonso. I think it was just a typical first lap incident where things get heated. Alonso was given one, moving his own tally to three - a driver is given an automatic one-race ban if they accumulate 12 points over 12 months.
Alonso confirmed in August he will be leaving F1 at the end of the ongoing campaign. He will complete the World Endurance Championship (WEC) 2018/19 season with Toyota, but it is now uncertain whether he will pick up a partial or full IndyCar programme alongside that.
