Sergio Perez says Force India lacked the pace to be able to fight for the podium places at the Belgian Grand Prix.
Perez started from fourth place but surged to second, briefly battling with Lewis Hamilton for the lead of the race.
Perez was soon overhauled by Nico Rosberg and later on by Romain Grosjean, while Daniil Kvyat got by late on due to running the Option tyres in the final stint of the race.
"Fifth place and ten points is a good result, but we just lacked the pace to really fight for the podium today," said Perez.
"My start was very strong and I was close to taking the lead on lap one when I was alongside Lewis after Eau Rouge.
"I settled into a good rhythm, but we had very high degradation on the soft tyres in the first two stints. It was a bit better on the medium, although we struggled in the middle sector with our low downforce set-up and that hurt my pace.
"We were racing some quick cars and it was hard to fight off Grosjean and Kvyat, so it’s clear we need to analyse our performance and see where we can improve.
"I’m already looking forward to the next race in Monza, which is another track where I think we can be competitive."
