Crystal Palace fans are sweating on the fitness of star man Wilfried Zaha today (Tuesday) amid reports that he has returned home early from international duty due to injury.

The 25-year-old is not involved for Ivory Coast today (Tuesday) as they take on Central African Republic in their latest African Cup of Nations qualifier in Bangui.

And reports emerging from Africa suggest that Zaha left the squad on Sunday to return to London, after contracting a slight injury in training on Saturday.

Linfodrome report that Zaha has an issue with his adductor muscle, which is the injury that forced him to miss Palace's 2-0 defeat at home against Southampton last month.

Zaha did play as Ivory Coast beat Central African Republic 4-0 on Friday, providing the assist for the Elephants' fourth goal, which was scored by Maxwell Cornet in Bouake.

There has been no official comment from Palace or the Ivory Coast about the reports of an injury, and there is no indication as yet as to the extent of the problem, ahead of the Eagles' trip to face Everton at Goodison Park on Sunday.

But Palace fans have been voicing their concern on social media, after a photo emerged on Instagram of Zaha back at Palace's training ground in Beckenham, ahead of today's game for Ivory Coast.

Some of the tweets from Palace fans can be seen below.
