Fernando Alonso was one of the best F1 drivers of this generation; but F1 boss Ross Brawn believes his talent deserved more race wins and more world titles.
Alonso has 32 race wins to his name and is a two-time world champion, but Brawn believes the Spaniard was capable of even more.
When Alonso moved to McLaren for a second time, the British team have struggled to compete, even in the midfield battle.
"I don't think Fernando won as much as his talent deserved, partly because he's never seemed to be in the right team at the right time, but he always stood his ground and took on his responsibilities," Brawn told F1's official website on the retiring Alonso.
"He will be missed, particularly by his fellow competitors, as all drivers - especially the top ones - know how important it is to go up against a worthy opponent. I think this was the thought that resulted in Lewis Hamilton and Sebastian Vettel forming a sort of guard of honour for the Spanish champion as they drove down the pit straight after the race and then put on a really spectacular show.
"In the past there were often arguments between Fernando and the other two, but in Abu Dhabi, respect was the prevailing emotion. Spinning around in clouds of smoke after the race were drivers who had 13 world titles between them, a notable achievement in the history of this sport and it was a moment that those who witnessed it will remember for a long time."
