Despite what many expected, the championship would hardly be considered boring with the McLaren onslaught peaking with the drivers fighting in several feuds. At Monaco, after Alain Prost set the fastest lap, Senna refused to accept that his teammate could be driving faster than he was, especially after Senna out qualified Prost by over a second. Senna pushed and after taking back the fastest lap, Ron Dennis got on the radio and told his drivers to effectively 'cool it' as Senna's lead was 50 seconds with only 12 laps remaining. Senna, his rhythm broken, then had a major lapse in concentration and hit the wall at Portier. What made Senna's mistake all the more astounding was that he had completely dominated the weekend, taking pole by 1.4 seconds from Prost (who was 1.2 seconds faster than Berger's 3rd placed Ferrari) and from the start of the race had simply run away and hid from the field.
