Jaime Alguersuari believes he could have finished in the points in the Abu Dhabi Grand Prix had it not been for a problem during one of his pit stops. The Toro Rosso driver finished in 15th position after losing a lot of time when he stopped to change tyres for the first time.
Alguersuari believes 10th place would have been possible.
"I am very disappointed with the outcome of this weekend, because we had opted for a strategy in terms of aerodynamics that appeared to be the best in terms of ease of overtaking in the race," said the Spanish driver.
"However, after the first four or five laps, I seemed to pick up some tire degradation and I was losing the rear end. Then came the key moment in my race, when there was a mistake in the pit stop, which cost me a lot of time and dropped me down the order, from which I could not recover.
"Today, P10 was possible, because I had a good pace on the new option [tire]s, even if I am not sure that we could have caught the Force Indias. I am sure Brazil will suit us better, so I am looking forward to that and the chance for all of us to do a better job."
Teammate Sebastien Buemi had to retire from the race after a strong start due to a loss of fluid from the hydraulic system.
