The Mirror have now reported that the relationship between the pair might not be quite as cosy as Clara's with Smith's Doctor though.
The publication has noted that Capaldi will have to "win over his sidekick Clara," before he goes to battle with the likes of the Cybermen, Daleks or Weeping Angels.
It's believed that Clara can't quite get to grips with Capaldi's new Doctor, and pines for the return of Smith, which results in the pair possessing a "spiky relationship" for the opening episodes.
A source added, "As a new Time Lord you need all the friends you can get, but he even has to win over his companion. Clara grew very attached to Matt and that shows in the opening episodes. Peter's Doctor has to get past a spiky opening and try to make Clara a sidekick who will help him save the world from the usual mix of aliens and monsters from the galaxy.
