Atletico Madrid honoured Juanfran before their game against Osasuna at the Wanda Metropolitano on Saturday evening.
The full-back left last summer after 355 games for the club and seven titles after arriving from Osasuna themselves in 2011.
During his stay in the capital, he was a key player under Diego Simeone.
Juanfran was presented with a plaque on the pitch ahead of the game on Saturday.
Atletico's fans unveiled a banner that thanked their former player for his service to the club.
