Sauber driver Sergio Perez has praised his team's strategy change after his podium finish at the Italian Grand Prix.
The Mexican raced from 12th on the grid to finish second in Monza behind Lewis Hamilton after choosing to start on the hard tyres.
The 22-year-old endured a poor qualifying performance but was happy to have learnt from the experience.
"I don't think we had the pace in qualifying for a single lap," said Perez.
"We were lacking too much speed on the straights.
"In qualifying I did not have good lap, I was too close to Bruno Senna, I lost downforce, that was reason not to be in top 10 but it helped us to change the strategy, we start on the prime and it worked quite well."
The next race is the Singapore Grand Prix, which takes place on September 23.
