Button says 2016 triple header on fair on F1 crews

Jenson Button has expressed concerns about Bernie Ecclestone's latest plans to populate the 2016 Formula 1 race calendar with an extra race.

After teams pushed for the restoration of the summer break and shutdown period, which had been diminished in the provisional 21-race schedule for next year, a revised draft calendar began to circulate the paddock.

According to France's Canal Plus broadcaster, it includes a 'triple-header' -- Singapore, Japan and Malaysia all paired together on subsequent weekends.

"This is not really a problem for the drivers," F1 veteran Button said, "but it's a different story for the teams. The mechanics and engineers already spend a large part of the year away from home, so this would be very hard on their families.

"Personally, I think three grands prix in a row is too much for formula one," he added.
