Herrera's caption of the Instagram post read: "Thank you great team #birthday."
The 22-year-old star is out of contract at the Parc des Princes next summer and there has been a standstill in the negotiation process between the player and the club.

Mbappe scored the side's second goal, but it was made clear that a number of the club's fans are less than happy with the striker's situation.
Meanwhile, Liverpool chiefs are reportedly planning to take advantage of Mbappe's precarious position with a free transfer next summer, but will they get their man?
