Arsenals hopes of signing France star Ousmane Dembele hinge on Barcelonas decision whether to send the winger on loan this summer.
The Gunners head of recruitment Sven Mislintat signed Dembele for Dortmund when the winger emerged as one of the most exciting players in Europe with Rennes in France.
Dortmund were powerless to stop Dembele joining Barcelona for around £110m in 2017 but the Frenchman had a difficult first season at the Camp Nou.
Mislintat believes Dembele is perfect for the Emirates but Barcelona are unwilling to let him leave permanently and the Gunners couldnt finance a deal for the 21-year-old.
However, Football.London claims the only possibility of Arsenal landing the winger this summer is if Barcelona allow him to leave the club on loan.
Unai Emery has made five signings so far since his appointment at Arsenal.

Bernd Leno, Sokratis, Stephan Lichsteiner, Lucas Torreira and Matteo Guenzouzi have all joined.
However, the Spaniard is determined to sign at least two more players but may have to offload the likes of Danny Welbeck and Nacho Monreal in order to raise funds for new arrivals.
