A few days after successfully defending his title against Viswanathan Anand, World Champion Magnus Carlsen granted an interview to FIDE Press Officer Anastasiya Karlovich.
Interview with Magnus Carlsen (14:26) 'After Winning World Chess Championship 2014'
Although Carlsen looks and sounds ill in the interview, he mustered the energy to give a frank account of his thoughts during the match. When asked, 'Which top players were helping you in this match?', he answered,
'Peter Heine Nielsen was here [in Sochi]' and Garry Kasparov was 'regularly in contact with Peter Heine'. Jon Ludvig Hammer, Laurent Fressinet, and Michael Adams 'were helping from home'.
Fressinet was Carlsen's opponent in the now famous video Too weak, too slow! (Youtube.com). As for 'Name three players who might be your opponents in two years',
The most obvious candidates are Fabiano Caruana, Levon Aronian, and Alexander Grischuk.
