Button thinks Perez would be a wise signing by any team that is on the market for an "intelligent" and "complete" driver.
Nov.21 (GMM) Jenson Button has given his departing McLaren teammate Sergio Perez a strong recommendation as the Mexican seeks a new seat for 2014.
The 2009 world champion has admitted he was surprised when he learned the great British team had decided to oust Perez after just one season in favour of the in-house development rookie Kevin Magnussen.
Perez, 23, is now struggling to find an alternate seat for next season, but Button thinks he would be a wise signing by any team that is on the market for an "intelligent" and "complete" driver.
"I feel that Checo has learned a lot this year," Button is quoted by France's L'Equipe.
"McLaren did a very good job in providing everything necessary for him to achieve his objectives," he added. "To absorb everything at once can be very difficult, but Checo was able to do it."
When asked his opinion about the young Dane Magnussen, Button said of his new teammate: "The decision about who is in the other car is not mine.
"All I can say is that Checo did a great job this year. Any team with a seat available should consider him, because he is not only fast, he's also intelligent.
"He is a complete package," added Button.
This weekend in Brazil, 33-year-old Button will become the most experienced British driver in Formula One history by competing in his 247th Grand Prix.
But at the end of an appalling season for McLaren, the Briton admitted he is not too excited about beating David Coulthard's old record.
"I am obviously doing something right if I've been around that long," Button is quoted by the Mirror.
"It's interesting more than anything else. Right now a podium would mean a lot more than reaching 247."
