Adding to the tension, Wolves manager Vitor Pereira expressed dissatisfaction with Cunha's "body language" during his post-match interview after the Chelsea defeat.
"He can be frustrated as he wants to win, but everyone in the dressing room wants to win," he told reporters.
"I don't like this body language. I want someone, as a captain, trying to help the team - running, suffering and fighting all together. But this is something I can understand. Next time, I won't understand."
When questioned about Cunha leaving the pitch immediately after the final whistle, Pereira added: “This is something I cannot understand. Again, it is the frustration - which I understand - but we need to be together. Together we can fix the problems and stay in the Premier League.
"If we start complaining about this and that, this is not the way. He is committed to Wolves but when you keep hearing about other clubs, then it is human [to be distracted]. (But)The team needs him with good energy and not with frustration. He must slow down and put his mind in the right way."
