Rio Ferdinand reunited with Sir Alex Ferguson ahead of Manchester United's clash with Everton.
Ferguson has attended Old Trafford and some away games regularly since his departure from United in 2013.
Meanwhile, Ferdinand left the Red Devils a year later to join QPR before turning to punditry on TNT Sport shortly after retirement.
The pair met in person for the first time in a while at Carington ahead of the visit of Everton and Ferdinand was delighted to see his former boss.
In a heartwarming clip posted by TNT, Ferdinand said: 'Boss! I can't believe you've come to see me, lovely to see you. How are you doing? You look well.
'I only normally talk to you on the text now, I don't normally see you.'
The pair then headed through sliding door to greet long-time receptionist Kath.
Ferdinand then told Kath: 'You didn't greet me like that, Kath! What's going on here?'
Kath replied: 'Of course I did.'
Ferguson joked: 'Do you know who he is? That's what gave me the white hair!'
Ferdinand was signed by Ferguson from Leeds for a world transfer fee for a defender in 2002 and would go on to play 455 times for United.
The 45-year-old enjoyed plenty of success under the Scotsman, winning six league titles, two leagues cups and the Champions League in 2008.
