Arsenal will face Roy Keane’s Sunderland at the Stadium of Light on Saturday.
“He has done well in his first year. You see already when he was a player that there are ingredients in there that make a manager,” Wenger said.
“A management career is a marathon, but he has the qualities to become a great manager.
“It does not surprise me at all that he had a good first season because he has played for a long time at the top level. After that it is down to stamina in the motivation – stamina to get over the disappointment because a career unfortunately is not only about carrying trophies.
“It is about being able to be motivated and to fight every day, to get over big disappointments and continue with exactly the same strength and power.”
