1990 Monaco Grand Prix

The 1990 Monaco Grand Prix, otherwise known as the XLVIII Grand Prix Automobile de Monaco, was the fourth round of the FIA Formula One World Championship, staged at the Circuit de Monaco in Monte Carlo on the 27 May 1990.'Monaco GP, 1990', grandprix.com, (Inside F1 Inc., 2015), http://www.grandprix.com/gpe/rr488.html, (Accessed 27/06/2019) The race would see Ayrton Senna secure his third career Grand Chelem in dominant fashion, as well as his third victory in the Principality.
The Brazilian ace had got his weekend underway perfectly, claiming pole position ahead of Alain Prost in the . Jean Alesi was next in the Pirelli shod , while Riccardo Patrese claimed the second spot on the second row.
Senna was not to be beaten at the start either, with the Brazilian racer streaking clear at the head of the field. His teammate Gerhard Berger would also make a storming start, only to collide with Prost at Mirabeau to block the circuit and stop the race.
The order was reset to how it had qualified, with Prost and Berger having to swap to their spare cars for a full restart. Once again, Senna would blast clear when the lights went out, leaving Prost to fend off Alesi into Sainte Devote which the defending Champion would manage to do.
This time the first lap would pass without issue, allowing Senna to establish an early lead at the head of the field. That meant all of the early action was to be found further down the order, with Nigel Mansell an early casualty, driving straight into the back of Thierry Boutsen having been stuck behind the .
Otherwise the order at the head of the field remained unchanged, until Alain Prost ground to a halt with an electrical issue mid-race. Alesi was hence left in a lonely second ahead of Berger, with Patrese chasing the second McLaren hard for a podium spot.
Patrese would ultimately become the final significant casualty of the race, as Senna cruised on to claim fastest lap and secure his third career Grand Chelem having also led every lap. Alesi was able to close up to the back of the Brazilian in the closing stages but made no serious attempt to pass, and hence finished in second ahead of Berger. 
The remaining points were shared between Boutsen, Alex Caffi and Éric Bernard, the latter two scoring for and respectively.
==Background==
Ayrton Senna had retained the lead in the Championship despite failing to score in San Marino, although his lead had been cut to just a single point. Indeed, both Alain Prost and Gerhard Berger had moved within a solitary point of the Brazilian after the opening three races, with a three point gap back to fourth place Riccardo Patrese. The top five was then completed by Jean Alesi, with eleven drivers on the score sheet.
In the Constructors Championship it was advantage arriving in Monte Carlo, with the Anglo-Japanese alliance a full ten points clear at the head of the field. Their closest challengers were on fifteen points, with the Anglo-French squad ahead of by virtue of having a third place finish compared to two fourths for the Scuderia. Elsewhere had moved into double figures, with and the only other scorers.
