Mercedes Team Principal Toto Wolff expects a much tougher challenge for the title from both Ferrari and Aston Martin Red Bull Racing next season, whilst also admitting that he feels McLaren will be stronger next term.
Mercedes were well clear of everyone else in 2019, with the Silver Arrows 235 points clear of second-place Ferrari.
“It’s fair to say that there are three teams capable of winning races today and probably winning championships if things are being put together," Wolff told the F1 Website.
“McLaren have massively caught up, probably the steepest performance slope of all teams and will be there or thereabouts, in my opinion.
“So, yeah, I see this very much as being a much tougher season.”
Mercedes secured their second-highest ever team total, securing 15 wins, 10 poles and 17 podium finishes.
