Jenson Button feels he could have challenged his team-mate Fernando Alonso in the closing stages but for a strategy slip up and leaves Hungary satisfied with McLaren's double points finish.

In an incident-packed Hungarian Grand Prix, the former F1 world champion says he was able to benefit from his rivals' misfortunes in the middle chunk of the race but after opting not to pit for fresh tyres during the safety car period Button's late charge became hamstrung.

"That was a tough one and a mistake but I still scored points," Button said. "I didn't stop for tyres under the safety car which pretty much everyone did which made it very difficult because the tyres were quite old at the end and primes while the others were on options."

Button also said he would have been able to challenge Alonso over the final ten laps but instead was caught by the Mercedes pair of Nico Rosberg and Lewis Hamilton, dropping from seventh to ninth. Despite his frustrations, the British driver leaves for the summer break happy with his team's results.

"As a team it is great to get points going into the break but we understood what was going on in the race with lots of offs and drive throughs which helped us but good to get points," he explained. "The start of the weekend we did target two points finish but at the lower end like ninth or tenth like I was. Fernando did a good job and the strategy worked for him putting on the soft tyres in the stint."

While upbeat with McLaren's best performance of 2015 he insists the Woking-based team is still on a long development path with Honda.

"The next two races are going to be tough. It is a step forward but we need another if we want to have this again."
