Wehrlein started the season with Manor after winning the DTM title in 2015, while Ocon joined the team halfway through the season after he too spent time racing in DTM following an impressive apprenticeship in junior formulae.
"These two are extraordinary drivers out of a handful of drivers I consider to be in the same league," Wolff told Autosport. "They’ve had two very different careers; one went into DTM and the other had an exceptional career in lower formula and GP3."
"From my perspective, they are both very different personalities and very equal in the race car. Both deserve to stay in Formula One and have a future."
He is expected to leave Manor, with Sauber favourites to sign him, despite their lack of customer deal with Mercedes.
