PSG star Lionel Messi has paid tribute to former Barcelona teammate Sergi Busquets.

The Barca captain has announced he will leave at the end of the season.

Messi posted to social media: "On the pitch always with the number 5, but in reality as a player and as a person you are a 10, Busi.

"I wish you the best in your new stage and always, both to you and to all your family.

"Thank you for what you did on and off the pitch, there were so many moments we spent together, many good ones and some complicated ones.... They will remain forever."
