GP Belgio, commenti post qualifiche–23/08/2014
Team-mate Kimi Raikkonen finished the session in eighth place and a full second behind Alonso.
The Finn admitted his final flying lap had been far from perfect.
"The car was pretty OK, but the conditions were quite difficult," Raikkonen said.
"I did quite a few mistakes in the last lap, I had to compromise my out-lap to get clear of traffic, so it was not the best way to start the lap and then I did some mistakes."
