Cesc Fabregas has been doing work with Jack Wilshere's U18 Arsenal squad.
The Spaniard, who is currently still playing for Serie B side Como, returned to London Colney to work alongside U18s manager Wilshere.
The academy manager, 31, posted a picture of the pair in Arsenal tracksuits at the training base to his Instagram story.
The former England international captioned the photo with a football and brain emoji and tagged the 35-year-old midfielder.
Wilshere played alongside Fabregas between 2008 and 2011 before the latter departed for LaLiga giants Barcelona.
The former West Ham and Bournemouth midfielder turned manager was also seen with Fabregas in January.
A previous Instagram post read: "Learning from the best football brain I know!
"As a player I wish I had the chance to play with this guy for longer but having the chance to pick his brain about certain situations and how he thinks about the game is invaluable. Thank you."
The former Chelsea midfielder replied: "Thanks for helping me out man. You are the best."
