The Portuguese manager, 52, is leading the Blues towards their fourth English Premier League title in his second stint at Stamford Bridge - two championships arrived during his original tenure.
Retired defender Ferreira, who followed Mourinho from Porto in 2004 before spending nine years in West London, believes his countryman's desire to succeed with Chelsea knows no bounds.
"When you are at this club you want to win titles and for next season it will be the same. The motivation is to win trophies," he said.
"He wants to succeed and do well, for how long I do not know. I think everyone at the club wants him to stay for a long, long time.
"I think everyone would like to see him in control for many years but in football, anything can happen."
While Mourinho remains the toast of the town and still has two years on his latest Chelsea contract, another recently returned club favourite could be on his way out this northern summer.
Didier Drogba has scored only three league goals since rejoining on a one-year contract last July, but Ferreira hopes the Ivorian striker, now 37, gets to experience a 10th season with the Blues.
Speaking on behalf of club sponsor Gazprom, Ferreira added: "I would love to see him stay for another season but I don't know what he wants or what the club wants from him.
"Let's see what happens at the end of the season.
"He has the motivation to keep winning and keep playing and I want to hear what happens at the end of the season."
Ferreira has been kept busy representing Chelsea as its European youth league ambassador but is also taking his coaching badges.
The 36 year-old has not ruled out pursuing a role within the Blues' training set-up at Cobham.
He added: "I've just finished my (UEFA) B licence so I need two more years to finish, I hope.
"At the moment I'm just concentrating on finishing and then let's see what happens. It's just important to have it and then, who knows?"
