Barcelona defender Jules Kounde has rapped Ilkay Gundogan after his blast for Ronald Araujo last night.
Gundogan called out Araujo for getting sent off in their Champions League quarterfinal defeat to PSG.
Kounde, later, posted to social media: "An immense disappointment not qualifying for the semis when we had everything to do it.
"By the way, we win as a team and we also lose as a team, always. It's time to recover and prepare for El Clásico this Sunday.
"Thanks for the support culers."
In the aftermath, Gundogan snapped: "I have not seen the replay and surely you will know better. It's hard to say, but at these crucial moments you must be sure that you can get the ball back. If you don't get the ball, and I don't know if he touches him or not, you should let it go.
"I prefer to award the goal or leave the striker one on one. He threw the long ball and I don't know if he got to the ball. He could leave the opportunity to our goalkeeper and save us or even award a goal. Getting one less man for a red one so early in the game kills you."
