The Ivory Coast international was a target for blame under Mauricio Pochettino but has been outstanding since the Portuguese tactician was appointed.
Aurier was one of the standout performers in their 3-2 win against West Ham United on Saturday, and produced another stellar performance in their 4-2 Champions League victory against Olympiacos, scoring and providing an assist in the encounter.
Ferdinand believes the arrival of the former Real Madrid and Chelsea boss has been a huge boost for the Ivorian.
“When a new manager comes in there’s sometimes one player who benefits, at the moment it’s him [Aurier],” Ferdinand told BT Sport.
“He was someone we were talking about as a car crash but he’s stepped up.”
Aurier, who has made 11 appearances this season, will hope to maintain his new-found form when Tottenham take on Bournemouth in their next league game on Saturday.
