Mitrovic told the Daily Mail: "Benitez plays defence and counter-attack. I tried to give my best but it wasn't me.
"I was just running and getting in the team shape. He told me what he wanted and I tried but I am 90 kilos and if I run so much defensively I have no power left when I am in the box. He knew I couldn't play in that style and I felt it too.
"Defensively he was one of the best and you can see that when they play, but personally I like to be close to the opponents' box. I need crosses and service. But Benitez is a great person and in the end I shook his hand.
"Newcastle is a big club but they have problems with the owner. Everyone knows Mike Ashley. They have taken large steps forward but also to go back. I do wish them success."
