Jenson Button has admitted to feeling a part of Spa's history after "a very special victory".

Button's 14th career win in Formula One was a lights-to-flag romp of a Belgian Grand Prix overshadowed by a first corner pile-up at the La Source hairpin that accounted for four drivers.

Championship leader Fernando Alonso was the biggest casualty, the Spaniard failing to score a point for the first time in 24 races.

Mercifully, Alonso was lucky to escape with his life in light of Romain Grosjean's Lotus flashing within inches of his helmet as the smash unfolded, suffering nothing more than pain in his left shoulder.

As the instigator of the incident Grosjean was later hammered by the stewards with a one-race ban that will see him sit out next Sunday's Italian Grand Prix.

Button's latest triumph, though, and Alonso's failure to score, has at least thrust him back into title contention. However, 63 points remains a considerable gap to overhaul with eight races remaining.

"This circuit is such a special circuit to most drivers with the way it flows," explained Button, who finished ahead of Sebastian Vettel and Kimi Raikkonen on the podium.

"So to get a win from lights to flag is very special, especially as it's not been the easiest year.

"And I just love Spa, I think we all do. It's really nice to win on a circuit like this. I remember watching F1 back in the day here – it was a little different then – and there's so much history. It's really good to be a part of that.

"So, yeah, a very special weekend. We're going to enjoy this for a little while longer before we head to Monza and hopefully do the same."
