"Well, Ney... I think we said practically everything to each other when you left," Messi began his message as he took advantage of the festive period.
The Argentine reflected on his time with Neymar before his £198 million switch to Paris broke up the formidable South American trio which also included Luis Suarez.
"The truth is that here we are still missing you. We would like to keep sharing the mates [a South American hot drink] in the morning with Luis [Suarez] in the dressing room and many more things," Messi added.
"Like always, I wish you the best wherever you are and I'm sure we will cross again on or off the pitch very soon. Take care of yourself."
