1990 Portuguese Grand Prix

The XIX Grande Prémio de Portugal, otherwise known as the 1990 Portuguese Grand Prix, was the thirteenth race of the FIA Formula One World Championship, staged at the Autódromo do Estoril in Estoril, Portugal, on the 23 September 1990.'Portuguese GP, 1990', grandprix.com, (Inside F1 Inc., 2015), http://www.grandprix.com/gpe/rr497.html, (Accessed 06/07/2019) The race would see Nigel Mansell register his first victory of the season, in a race that was stopped prematurely after a huge accident between Alex Caffi and Aguri Suzuki.
Qualifying would see cause something of a shock, securing a front-row lockout with Mansell on pole ahead of teammate Alain Prost. that left the two s of Ayrton Senna and Gerhard Berger on the second row, while Riccardo Patrese shared the third with Nelson Piquet.
The race would be heralded by a late withdrawal for Satoru Nakajima, who crashed heavily during the warm-up having come down with flu overnight. That left 25 cars on the grid for the start, which saw Mansell make a mess of his getaway, slithering across the circuit after jumping on the throttle too heavily.
Indeed, Mansell's launch was such a mess that he also carved up teammate Prost, meaning the two McLarens of Senna and Berger could surge ahead to claim the lead. Piquet was set to follow them through but was ultimately blocked by Mansell as the Ferrari slithered back across the circuit, leaving Prost down in fifth behind the Brazilian.
The order remained fairly stable at the head of the field, with Prost stalking Piquet as the top three pulled clear ahead. Indeed, it was only after lap thirteen that the Frenchman finally made a move stick, before quickly dropping the Brazilian to latch on to teammate Mansell.
Mansell was not having a particularly good afternoon, with another throttle related slide allowing Prost to slip ahead of the Brit on lap 26. However, the Brit's race was to be vastly improved after the stops, with Mansell emerging in second behind Senna, with pair pulling clear of the now third placed Berger.
With 20 laps to go Mansell was in position to attack Senna for the lead, and duly sent his Ferrari diving inside the McLaren to claim the top spot in the field. However, moments after securing the lead Mansell received a major scare, clipping Philippe Alliot at high speed as the Frenchman drifted across the Ferrari's nose.
That collision would send Alliot shooting into the barriers, while Mansell briefly eased his pace to check if his car was damaged. Somewhat miraculously his Ferrari was unscathed, allowing him to pull clear of a rather quiet Senna, who steadily drifted back towards a charging Prost, who had barged past Berger despite losing sixth gear.
The top four would close up in the closing stages of the race, although there was to be no four-way scrap for the lead. Indeed, the race was ultimately stopped with ten laps to go after Suzuki and Caffi crash heavily at Curva 2, leaving bits of and scattered across the circuit.
The race result was officially declared at the end of lap 61, leaving Mansell as the victor ahead of Senna and Prost. Berger was classified in fourth ahead of the two s, with Senna moving eighteen points clear at the top of the Championship with three races to go.
==Background==
Ayrton Senna had moved sixteen points clear at the head of the Championship after his sixth win of the season in Italy, but was only two race scores away from having to take dropped points. Alain Prost, meanwhile, would have to win two races out of the remaining four just to get level with the Brazilian, although he had three races to go before he began dropping points. Gerhard Berger was next, and out of the title fight with 37 points, while Thierry Boutsen and Nelson Piquet completed the top five.
 left 's home race with a handsome lead in the Constructors Championship, having moved 37 points clear of the Scuderia. Indeed, McLaren would win the Championship in Portugal if they outscored Ferrari by eight points, with Ferrari having to win every race remaining in the season just to challenge. Elsewhere, had solidified their hold on third over , while completed the top five.

==Standings==
Ayrton Senna moved eighteen points clear of second placed Alain Prost at the head of the Championship hunt with three races to go, meaning he could win his second World Championship next time out in Spain. Indeed, if the Brazilian out-scored the Frenchman by a point in Jerez he would claim the crown, with Prost realistically needing to win to stand any chance of challenging at the end of the season. Those two were now mathematically the only drivers in the fight, with Gerhard Berger, Thierry Boutsen and Nelson Piquet completing the top five.
In the Constructors Championship it had remained advantage , although their lead at the head of the field had been cut. Indeed, had done just enough to keep their title challenge alive for another weekend, although if the Scuderia failed to out-score the Anglo-Japanese alliance by more than three points in Spain then the title battle would be over. Elsewhere, had closed right onto the back of third placed , while rounded out the top five.
