The Armenian has battled for minutes this season.
“I think Micki will work here for sure,” Mourinho said.
“I don’t like to speak about players from other clubs because I don’t want to be misinterpreted, but I don’t think he’ll mind. A player who had a problem to play when he first arrived was Willian. He went through a process and then, after a few months, he became a top player. Then, when we won the championship, he was phenomenal and still is. That is just an example.
“Similarly, Di Maria had to learn a lot about his game when he came into Madrid from Portugal. Sometimes this is what happens. It happens with defenders, but it is often easier for them to adapt than attackers. Some go straight to success and others it takes more time.
“In Micki’s case the process was interrupted by injury, which does not help the process of evolution. Being out for a month meant he has had to go through the process of getting match-fit, then once he has that he needs the competitive level to do it. We believe him and, sooner or later, there will be no problem.”
