Keen reckons the Academy graduate is benefiting from regular conversations with former Premier League Golden Boot winner Anelka.
“Nico’s a great part of the squad - he’s a super person to have around the place,” said Keen to the WBA website.
“His qualities are still there for everyone to see.
"The work he does day in, day out, helping someone like Saido, who sees his movement, touch and finishing.
“There is no doubt the likes of Saido and Matej Vydra will improve because of that, as Romelu did last year working with the likes of Shane Long, Marco Fortuné and Peter Odemwingie.
“So, with Nico, it's not just what the media or supporters see on a Saturday."
