PHOTO: Park Ji-Sung & Sir Alex Ferguson reunited at Old Trafford

The former Manchester United duo posed together before the Everton game.

Remember the old days? Not too long ago but just a few years back, when Sir Alex Ferguson would be watching from the sidelines as Park Ji-Sung ran and ran tirelessly for Manchester United.

It seems an age ago, really. But United supporters were offered a reminder of those times earlier today before Louis van Gaal's side took on Everton.

Indeed, Park, now a club ambassador for United, posed for a photo with his former manager, no doubt leaving plenty of fans nostalgic. 

"I’m very happy to be back," Park told Manchester United's official website upon his return to the club.

"I got very used to Manchester - its atmosphere, its weather - when I played here so it's very familiar to me. I felt very comfortable when I got off the train today.

"I thought my relationship with Manchester United was finished because it’s a huge club and I am just one of the many players who come in, play here and then leave.

"So when the club asked me to become an ambassador, I couldn’t believe it but of course, I was happy to accept. It’s a huge, huge honour for me."

A sight to behold for Man United fans.
