Wolves stars Mario Lemina and and Matheus Cunha posted their disappointment at a Premier League loss on Monday.
The duo were involved in the club's controversial 3-2 defeat to Fulham in the top flight on Monday.
Despite the result, Wolves are still in a solid position in the table, but Cunha and Lemina wanted to see better refereeing in the game.
Taking to Instagram, Lemina posted on his story about a game that saw significant refereeing controversy: “I've always tried to understand that to referee, it's not easy at all, I've always tried to say to the players that we could do better during the game to win it.
“But now I give up. Enough is enough. Some strong decisions need to be taken. These things are ruining football."
Cunha posted: “Tough result but we continue together. We will never look for excuses outside, but some decisions against us have to bear greater responsibility.
“We are tired of hearing excuses the next day. We will never look for excuses outside, but some decisions against us have to bear greater responsibility. We are tired of hearing excuses the next day. You harm the work of several families."
