Lazio's Keita Balde Diao has blasted coach Simone Inzaghi for publicly questioning his commitment to the team after supposedly exaggerating an injury.
On Friday the Lazio manager pulled no punches when discussing his disappointment at the 21-year-old's request to be left out of the squad travelling to Atalanta due to a knee injury, claiming that tests showed no signs of one.
The former Italy international continued by saying that he wants to work with players "who want to win and are proud to wear the Lazio shirt".
On Saturday the newly-capped Senegal international retaliated, taking to Facebook to defend himself.
"I won't let anyone doubt my word," he wrote.
"I have a knee problem and, after a medical check-up for a nasty knock, I was told not to risk it against Atalanta. It's strange that someone who was a player and felt these sensations doesn't understand.
"I am a professional and I live to play football. I wanted to go to Bergamo to prove it. As I said in the past, I will always give my best for this club, to the last second of my adventure and my contract.
"That's even if, as you can see, they try to put a spanner in the works every time. At this stage it's clear that someone thinks with these methods they can force me to do what they want.
"I've already said many times what I think. Despite not agreeing with this approach, I will give everything for Lazio and its fans. Because I am proud to wear this shirt and I play for Lazio, not for a project or someone else's interests."
