The Tottenham manager expects his former mentor to attract a lot of attention next season, having completed his long-awaited return to Stamford Bridge this summer
The Special One returned to Stamford Bridge this summer after a disappointing season with Real Madrid in which he fell out with senior players and failed to win a trophy.
But Villas-Boas - who worked under Mourinho at Porto, Chelsea and Inter - believes his former mentor's talent and charisma means he will remain compulsive viewing.
"It won't be possible to take your eyes away from Mourinho," he told Portuguese newspaper O Jogo.
"One of his characteristics, and I don't say it in a negative way, is to deviate attentions, positive and negative, in such a way that the team is only worried about winning."
