Although Sebastian Vettel has backed Fernando Alonso to be his main rival this season, the German reckons Felipe Massa could also pose a threat
Alonso led Ferrari's title challenge in 2010, his first season partnering Massa the Scuderia. However, he fell short, losing the title by four points to Vettel in the season finale in Abu Dhabi.
Massa, in contrast to his team-mate's performances, struggled after appearing to lose motivation in the wake of Ferrari's team order debacle. He finished the campaign 6th in the standings on 144 points, 108 points behind Alonso.
Vettel, though, reckons the Brazilian could bounce back this season, although he's not the only driver the Red Bull racer is tipping to succeed.
"Alonso for sure, and Hamilton is without question one of the best drivers," Vettel told Sport Bild when asked about his main rivals.
"Massa didn't have a good season (last year) but do not underestimate him; it's not so long ago that he was really strong.
"Schumacher's history is too great to write him off as well. I think neither of them have forgotten how to drive, and Nico Rosberg has also showed us his strength."
