Sebastian Vettel admitted that he simply didn't have to pace to challenge the front-runners at Spa on Sunday.
The four-time World Champion started in third place in Belgium and made a flying start to the race, passing Nico Rosberg and challenging Lewis Hamilton for the lead, before dropping back again.
Subsequently, Vettel was also passed by his team-mate Daniel Ricciardo and lost further position to Valtteri Bottas and Kimi Raikkonen during the first round of pit stops.
In fact, were it not for a late salvo that saw him pass Fernando Alonso and Kevin Magnussen on the final lap after the trio and Jenson Button were involved in a tight scrap for fifth that took place over several laps, Vettel might have finished further down the track.
Speaking to the BBC after the race, Vettel admitted that his car wasn't working as well as that of his team-mate Ricciardo.
"Disappointed because we didn't have the speed today. I was trying to put Lewis under pressure from the off, we were set up for straight lines but the tyres were colder than expected. Lap two was good to see the two Mercedes hit each other and give us a chance but I just didn't have the pace," Vettel said.
