Wenger singled out Gibbs for praise after the injury-prone left-back, now fully fit again, scored a spectacular goal at Swansea in the FA Cup last Sunday.
"Kieran's now more stable after some injury problems and you feel, when he expresses himself, there's much more to come out. He creates danger because he's a full-back who can dribble.
"This guy has massive potential. He's starting to show it now."
