Teams will be interested in Pidcock's skillset, certainly, but Ineos gave him an inflated contract on account of his potential and being British. This will hamper negotiations.To which GT, for Tour you have Tudor, Total and UNO X already for 2 spots, for the Giro you have basically 3 teams that are guaranteed the 3 spots that are free (Tudor, Bardiani and Polti) and for the Vuelta you have multiple Spanish Pro Conti teams for only 2 spots (Caja and Burgos their turn next year). Unless either Israel or Lotto skips the Vuelta (chances are really small) there's no extra spot. So the chances Q36.5 gets a WC to any GT are almost 0, even with Pidcock and maybe rumored Kwiatkowski (option according to Gazzetta).
Apart from Q36.5, Red Bull (this is known, but they are trying to get Van Gils for that position), Astana (they will definitely be interested but does he wants to go there) and even Visma are interested according to Benson. Of course teams are interested in Pidcock, really doesn't matter that he's maybe somewhat disliked. You think teams like Astana care lmao.
As for personality issues, apparently that is what got Pidcock's contract terminated. Even Rohan Dennis struggled to achieve that.
