The defender was outstanding in victory at Champions League opponents PSG this week.
Wales coach Giggs told Webby & O'Neill's YouTube channel: “First of all, he's a really good lad with a good mentality.
"All Axel's got to do now is stay fit, play games because he's got all of the attributes. He can handle the ball, he can even play in midfield.
“We thought about playing him in midfield when he was fit, under Louis (van Gaal).
"He can read the game well, he's quick - I think he showed that yesterday (against PSG)."
