Nemanja Matic says Jose Mourinho's quest for success at Manchester United means he will never get too comfortable at Old Trafford.
After helping Chelsea to win their second Premier League crown in three years, the 29-year-old moved north in the summer to re-join his former manager.
No outfield player has played more league minutes for United this season than Matic and the Serbia international is relishing the demands put on him by Mourinho.
"He always wants the best," Matic said ahead of the trip to Crystal Palace on Monday live on Sky Sports. "He always wants to win.
"Of course, him as a coach, if you play good he always thinks that you can play better. This is good. He always asks you to do more.
"I am happy that we work with him and he's a coach who won many, many trophies in his career and for sure we can learn a lot of things form him.
"He won many things. The coach is good if he won the trophies. He won in every country he has been, he has won a lot and that's why they call him special."
Mourinho oversaw Europa League, EFL Cup and Community Shield success during his first campaign in the United dugout, while his reinforced side are now dreaming of FA Cup and Champions League glory.
Matic is as realistic as his manager when it comes to making up the Premier League deficit given Manchester City's sizeable advantage, but the midfielder also shares his manger's determination to keep plugging away.
"I am always positive," he said. "Obviously the gap between us and City is big, but we will fight until the end."
