Cape Town - Red Bull advisor Dr Helmut Marko has tipped Sebastian Vettel to "come back even stronger" after the summer break and clinch a fifth World Championship title.
Vettel currently holds a 14-point World Championship lead over main rival Lewis Hamilton after bouncing back from his Silverstone nightmare with victory in Hungary.
And Marko believes that win will see him come back more determined than ever to ensure he finishes the job in the second half of the season.
"Seb will use this summer break to come back even stronger – that's how I know him," Marko told the official F1 website after being asked for his pick for the title.
"I believe in Vettel, because I know his mental strength, and Ferrari has raised its game,"
"Ferrari was clearly the stronger car in the first half of the season and only due to various circumstances could they not materialise all their chances.
"Silverstone, I would say, was an exception."
