Dinamo Zagreb youngster Dani Olmo has reportedly emerged as a potential transfer target for Barcelona.
The Catalan giants are known to be in the market for established names this summer after being linked with Matthijs de Ligt and Antoine Griezmann.
However, it appears that the La Liga champions are also considering whether to secure a reunion with a player who initially left the club in 2014.
According to Marca, Barcelona are interested in bringing Olmo - currently impressing for Spain Under-21s at the European Championship - back to Camp Nou this summer.
The 21-year-old contributed 12 goals and nine assists during the most recent campaign, helping Dinamo to yet another league crown.
Bayer Leverkusen are also said to be looking at a potential deal for Olmo.
