Liverpool manager Jurgen Klopp has admitted that his side will have to accept any punishment they receive if they are found guilty of fielding an ineligible player in the Carabao Cup.
Klopp's side beat MK Dons in the third round to progress to a tie against Arsenal in the last 16, but in the match against the League One team, Spanish midfielder Pedro Chrivella was selected without the proper international clearance.
In a worst-case scenario for Klopp, Liverpool could be expelled from the competition following the EFL's investigation.
And Klopp says that while he is unsure if they have committed any wrongdoing, they will take any punishment the EFL see fit to give them.
"I cannot say too much about it because other people are working on it," Klopp told reporters.
"What I can say if it was our fault alone, then we have to be punished. It didn't happen on purpose but my only really concern is the player.
"He couldn't play for half a year in Spain [on loan at Extremadura] and if he can't play for us from now on that is the biggest problem.
"[If] we made a mistake, and I am not sure if we did, but if we did the player should not be punished."
Sunderland were previously found guilty of fielding an ineligible player in 2014 when Ji Dong-Won appeared after returning from a loan spell without proper clearance. However, the club were not thrown out of the cup.
