John Terry made his Chelsea first-team debut 20 years ago this month.
In fact, it came on October 28, 1998 as he was a substitute against Aston Villa - with whom he's currently an assistant head coach - in a League Cup tie at Stamford Bridge which ended 4-1 to the hosts.
And one member of the current Blues squad who has followed in Terry's footsteps in terms of coming through the ranks at the club had a superb message for the former defender.
To mark the occasion, Tammy Abraham sent the Blues legend a picture of the club's academy players watching that exact game from two decades ago.
The twist being that the players were babies at the time and were watching from their cots - something which made Terry feel rather old.
When @tammyabraham1 sends you this pic and makes you feel old," Terry wrote on Instagram and tagged Callum Hudson-Odoi, Mason Mount and Recce James.
He then brought up a brilliant and hilarious point about Ruben Loftus-Cheek, Fikayo Tomori and Abraham.
"You 3 shouldn’t have been up that late watching the game," he added.
This prompted every player tagged in the photo to respond.
Abraham said: "I keep laughing at this."
Mount replied with: "That's brilliant."
Loftus-Cheek had the real question: "Am I the only one wondering why we have beards and are sleeping in cots?"
Tomori said: "Love it." James said: "Class." While Hudson-Odoi reacted with a few laughing emojis.
Even Blues assistant head coach Jody Morris found the image funny as did Willian.
