Jose Mourinho has called his new signing Nemanja Matic “a genius” who “thinks football” following the midfielder’s debut this week.

Matic was in United’s starting line-up for their 2-1 win over Sampdoria in Dublin. He joined United for £40 million from Chelsea earlier this summer.

However, Matic lasted just 45 minutes and Mourinho has said that he is still lacking full match fitness, “He needs time but [his] experience, intelligence, a genius in the way he thinks, he thinks football. We will help him to be ready sooner rather than later.’”

Mourinho also said that the club has done a “fantastic job” in securing three of his four transfer targets this summer.

In the same interview he called the two-game ban given to Phil Jones for a breach of UEFA’s anti-doping regulations as “very unfair”. He said that UEFA failed to show common sense, “He wins a European cup, he wants to celebrate with his team, he wants to get the cup, the medal, he wants to be in the pictures, and one doctor wants to close him in a small room because of the doping control. I think it’s very hard to control a player in this situation and UEFA should take that into consideration.”

Mourinho said that in exceptional matches, such as finals, it would be better for the doping control committee to place someone on the pitch with players so that they can see that there is nothing wrong other than a “human desire to celebrate”.

He believes that any player in the same situation would react in the same way and encouraged Jones to appeal saying that “it’s quite unfair but when you do that you have the risk of more punishment. I don’t know, it’s a decision I leave with him.”
