The Manchester City defender caught the Tunisia forward in the face in the 35th minute of England’s World Cup opener in Volgograd on Monday, although protested his innocence, and was shown a yellow card before Ferjani Sassi coolly slotted home.
The former Denmark international believes Walker should have been sent off for the foul, although was happy to see England come away with three points after a 2-1 win.
He told Russia Today: “It was a penalty, there is no doubt about that. He actually hits him and he is very, very lucky to get away with a yellow card because according to the rules, if you hit someone with your elbow, you’re off – it’s a red card.
“They got there in the end. I feel very happy for the England boys because if they hadn’t have gotten there, the next couple of days would have been terrible for them. They would have been crucified by the English media.
“I’m not sure that they are going to go completely free because the second half was awful. The way they played in the second half is not promising for the next few games in the tournament but in the first half, they created so many chances.
“Jesse Lingard created four chances and should have scored all four. Harry Kane is the one guy they need the chances to fall for because he scores them.”
