Antonelli tops FP2 as Gasly crashes heavily at Spa

Norris is one of a number of drivers who face a grid penalty this weekend, after exceeding his permitted number of batteries.

He is joined by Red Bull's Isack Hadjar, fifth fastest overall behind Lewis Hamilton's Ferrari, and Aston Martin's Lance Stroll.

The championship gap has closed largely because of problems for Antonelli, who retired from second place in the Barcelona Grand Prix, and lost a probable victory at Silverstone last time out by a wheel fairing failure and then a penalty, which dropped him out of the points.

Russell also took an impressive win in Austria, just fending off Verstappen and Antonelli, for his first victory since the first grand prix of the season in Australia.

Behind the top six of Antonelli, Norris, Verstappen, Hamilton and Hadjar, McLaren's Oscar Piastri, Alpine's Franco Colapinto, Russell and the Racing Bulls of Arvid Lindblad and Liam Lawson completed the top 10 ahead of Ferrari's Charles Leclerc.

Verstappen was complaining about gearshifts, as he so often does, but his pace was encouraging considering the team have had to shelve their 'flip-flop' rear wing after consecutive crashes for the Dutchman in high-speed corners in Austria and at Silverstone.

The failure was that the wing was closing too much, removing the so-called 'slot gap' between the main plane and flap, meaning the car had less downforce than the driver expected on corner entry.

Reverting to the standard wing, which opens like the old DRS overtaking aid, is said by insiders to cost around 0.2secs a lap.

Technical director Pierre Wache said: "It is a mechanical problem that we spot after the accident in Silverstone. We fixed it. It [the car] should be ready and bulletproof.

"I don't want to be too precise on what we are doing because it is a performance benefit to use it. But we take it seriously, we discuss with the FIA because it is our duty to make the car safe and you will see the wing back soon."

Red Bull hope to have a revised version of the new wing ready for the Hungarian Grand Prix next weekend.

Racing Bulls have an upgrade on Lindblad's car this weekend. The team decided to give it to the Briton rather than Lawson after an agreement that the driver who qualified ahead at the British Grand Prix would have the new parts for Spa.

Lawson will get the next upgrade later in the year, which is also expected only to be ready for one driver initially, team principal Alan Permane said.
