His debut at McLaren ruffled feathers, as he outqualified Senna for the 1990 United States Grand Prix obtaining pole position. Initially, Berger complained of a lack of space in the &lt;a href="McLaren%20MP4/5"&gt;McLaren MP4/5&lt;/a&gt;B for the 1990 season, which had been designed in 1988/89 for the shorter Senna and Prost. At the 1990 Canadian Grand Prix Berger finished first, around 45 seconds ahead of the eventual winner Senna, but was penalized by one minute for creeping at the start before the green lights. Berger also started from pole position at the 1990 Mexican Grand Prix. In 1990 Berger failed to win a race for his new team, while teammate Senna won the Drivers' Championship for the second time.
