Arsenal teenager Dan Crowley has joined Barnsley on loan until January.
The 17-year-old midfielder moves to League One to gain first-team experience.
Barnsley claim to have beaten a number of clubs to the signing of "one of the best young players" in Europe.
"He is an exceptional and exciting talent who is very highly thought of at Arsenal and we are extremely pleased that we have been entrusted with his further development," Tykes head coach Lee Johnson told the club website.
"This loan signing further evidences that Barnsley can persuade some of the country's best young talent to come to us, even where there is stern competition. Undoubtedly, at just 17 years old, Dan is one of the best young players in his age group in Europe."
Crowley is yet to make his senior debut for Arsenal.
