Graham Hunter told Revista that leading Real Madrid to the La Liga trophy represents Jose Mourinho's greatest triumph as a manager.
The Portuguese's team amassed 100 points this term to wrestle the Spanish top-flight crown away from Barcelona for the first time in four years.
Mourinho has now won domestic titles in four countries, as well as winning the Champions League with both Porto and Inter Milan.
But Hunter believes the self-proclaimed 'Special One' should be most proud of his success with Los Blancos, considering the problems he encountered over the course of this campaign.
"There were divisions within the dressing room and however glorious this season has been, there is no point in denying that," said Hunter.
"Mourinho was booed by his own fans, he lost to Barcelona in two trophies and Real then went out of the Champions League.
"To win with such style, break so many records and unify a dressing room, which wasn't feeling that positive about him all the time, might be his most magnificent achievement."
Real - who netted a whopping 121 La Liga goals during the 2012/13 season - finished nine points ahead of Barcelona in the final standings.
And Hunter's fellow Revista pundit Gerry Armstrong thinks Mourinho's men will be the team to beat in the Spanish top flight for the foreseeable future.
"I feel there could be a change of power now," said the former Mallorca player. "The momentum is with Real Madrid; they have the credibility, the belief and their squad is immense.
"Barcelona have it all to do. 90-odd points would normally win you any league title in any country but not this season because Real Madrid are so strong in every department.
"I think they have the power within their hands to continue for many years. It is quite a young side and they could dominate."
Terry Gibson, however, is anticipating a close-run battle for the La Liga title over the coming campaigns between Spain's most decorated clubs.
And the ex-Coventry and Wimbledon striker says Madrid may have to strengthen their rearguard during the summer if they are to stay ahead of Barcelona, who will be managed by Tito Villanova next term.
"There was no denying that Real Madrid were more motivated to win the league this year, but it is too early for us to say that they are in a position to dominate," said Gibson.
"Barcelona have not got too much wrong and for the next couple of seasons it is going to be nip and tuck.
"I would look at the centre of Real's defence. Sergio Ramos is brilliant at centre-half but I think he would be better for Real Madrid at right-back.
"I don't trust Pepe in the big matches and I think they can do better, while Ricardo Carvalho and Raul Albiol haven't been used much, so there is probably room for manoeuvre."
