Abu Dhabi: Sahara Force India driver Paul di Resta on Thursday said he is surprised by Nico Hulkenberg's decision to join Sauber since the Indian team has been more consistent than their close rival, this season.
Sauber on Wednesday confirmed signing of Hulkenberg for the 2013 season.
"I was surprised that Nico left this team, to be fair, for an immediate competitor. I don't see it as being a step up, to be perfectly honest. I see it as an equal kind of status," the Scot, who has been with the Indian team since 2010, said.
