Pierre-Emerick Aubameyang has been an instant hit with Arsenal since his January move.
The former Borussia Dortmund striker has 19 goals in 28 games so far and scooped the Premier League Player of the Month award for October.
And it's fair to say the 29-year-old hasn't even hit his finest form for the Gunners yet, with the striker still adjusting to London life and the Premier League.
What a player he'll be when he fully settles.
Nevertheless, his season has been littered with injury niggles so far and it seems Aubameyang is still suffering from pain his back.
Aubameyang will not play for Gabon in the 2019 Africa Cup of Nations qualifier against Mali on Saturday.
But it seems Gabon haven't actually disclosed that the Arsenal striker is absent through injury.
And Aubameyang feels like he's been left out to dry, making his feelings towards the Gabon FA known.
"It's bizarre," he fumed. "Any FA will publish the reason why one of its players can't report for international duty.
"But in this case, our association definitely received an e-mail from my doctor (saying I am injured). However, they still haven't made this fact public.
"People are going to say that Aubameyang declined to turn up. It looks as though I have refused to come along for a different reason."
You can understand his frustration.
Aubameyang has played 58 times for Gabon's senior side, scoring 24 goals in the process.
The Arsenal striker is the African nation's poster boy and they will struggle against Mali without him.
A loss on Saturday could allow Burundi to move into second place in the group - assuming they beat South Sudan.
Arsenal fans will simply be hoping Aubameyang's back injury is not too serious, with the Gunners travelling to high-flying Bournemouth in two weeks time.
