Vitor Pereira questioned why Matheus Cunha’s goal for Manchester United was not disallowed for a handball by Bryan Mbeumo.
Cunha scored his side’s second in a 3-2 win for United, despite the ball striking Mbeumo’s hand before his team-mate fired in.
“It’s a pity that, in the end, the game was decided by a decision that,” Pereira said. “Okay, I must accept because it’s the decision of the referee, but it’s not my opinion. For me, it’s handball. Very clear.
“But he decided not to cancel the goal and for me it was the decision that decided the game.
“I think that he thinks the control in the end was after the touch on the body. I think I must accept but it’s not my opinion. I watched the images and in my opinion, he controlled the ball with the hand and the goal comes from the control.
“If not, they will not have a chance to shoot and score. But in the end this is the doubts we have in this moment in the Premier League about the decisions.
“Handball, we don’t know what is handball or not. The blocks in the box for free-kicks, we don’t know if it’s a foul or not. I think it’s important to have a meeting with everybody and try to understand the rules, the decisions, because I think everybody, all the managers in this moment have doubts about some decisions.
“If the game today was decided in this way and we still needed the points to be safe, there’s a big problem.”
