The Israeli tactician was appointed as Portsmouth’s new director of football on Tuesday.
Grant held a similar post at Fratton Park between June 2006 and July 2007.
“I love Avram, genuinely. What a great guy,” James told Sky Sports News.
“When I joined the club he was there and he was very active in a lot of the preparation for games.
“He is a very wise man. His football knowledge is extensive and on top of that he is a good bloke, so it’s a good move.”
