Bakary Sako, winger for the Eagles, celebrated his birthday on Thursday along with two footballing friends.
As well as Palace team mate Christian Benteke, Arsenal striker Pierre-Emerick Aubameyang was with Sako on the day he turned 30.
Aubameyang paid tribute to Sako on Instagram, as he shared a picture of him with the two Palace players, saying ‘Happy birthday la miff’, a nickname for the winger.
The picture was taken earlier in the day on Thursday, as Aubameyang later made his way to the Emirates Stadium to watch his Arsenal team mates in action.
Aubameyang was ineligible for the Europa League semi-final, after joining from Borussia Dortmund for a club record £56million in January.
He could only look on helplessly as Arsenal conceded a late equaliser to draw 1-1 in the first leg with Atletico Madrid.
Sako himself later sent a thank you message via Instagram to everyone who had wished him well on his 30th birthday.
He wrote: ‘Just wanted to thank all of you guys for all the birthday wishes. Let’s celebrate on the weekend hopefully with a win as well so the party will be even better.’
