The 18-year-old spent time on loan with League One side Barnsley this season, with then manager Lee Johnson describing him as one of the best 18 year olds he had ever worked with.
Crowley was recalled though by Arsenal, but has yet to break into a Gunners team which is top heavy with midfield talent.
A loan move to Derby County, who try and play excellent football themselves, would suit him down to the ground.
Crowley is definitely a hot property in English football at the moment, representing his country at all levels up to under-19 already.
If Derby could prize Crowley away for a month or two, he could be just the boost the flailing Rams need as their promotion charge is stalling.
