Santon played under Mourinho for two years during his time with Inter Milan before joining Newcastle last year.
Since then, Pardew has guided the Magpies to an impressive fifth-place finish in the Premier League, and Santon believes that his methods are similar to those of 'the special one'.
"Pardew is a great coach with a lot in common with Mourinho," he told Gazzetta dello Sport. "He's scrupulous, he teaches football, he knows tactics and opponents," said the 21-year-old.
"The first few months were not easy. I didn't speak the language and coach Pardew kept me on the bench for some time.
"He explained I have to study the Premier League. He was right, he protected my integration."
Newcastle's next match comes against Manchester United on Sunday.
