Biggest issue is his lack of final product at the end of those dribbles. Only 6 players in Europe's top 5 leagues have completed more dribbles, but here are the rest of their stats in comparison:
Neymar - 4.8 (13 goals, 6 assists)
Ben Arfa - 4.6 (5 goals, 2 assists)
Saint-Maximim - 4.3 (6 goals, 2 assists)
Boufal - 4.2 (2 goals, 2 assists)
Januzaj - 4.1 (0 goals, 3 assists)
Messi - 3.8 (25 goals, 11 assists)
EDWARDS - 3.6 (2 goals, 2 assists)
Compared to the top 5 in completed Premier League dribbles:
Hazard - 3.2 (12 goals, 10 assists)
Zaha - 3.2 (7 goals, 2 assists)
Sterling 2.7 (12 goals, 9 assists)
Redmond - 2.3 (3 goals, 2 assists)
Traore - 2.2 (1 goal, 1 assist)
Although it's also worth noting that the defending in the Eredivisie is borderline pathetic. If we DO decide to loan him out though, I think we could do a lot worse than sending him off to Ligue 1 (or preferably the Bundesliga) which are both higher level with better opposition.
