Dimitar Berbatov returned to Manchester United on Thursday to train at Carrington.
The former Red Devil is currently a free agent and has returned to Manchester to build up his fitness and observe Jose Mourinho's training techniques with plans to one day move into coaching.
Berbatov posed alongside former strike partner Wayne Rooney at United's AON training complex and shared it to his two million fans on Facebook.
The striker spent four seasons at Old Trafford and was a popular figure, scoring 56 goals in 149 appearances for the club.
