Manchester City’s Raheem Sterling has issued an apology to referee Viktor Kassai after he won a comical penalty during the team’s 6-0 victory over Shakhtar Donetsk on Wednesday.With the Premier League champions 1-0 up in the first half, Sterling burst into the area and tripped over as he tried to dig his foot under the ball to chip Andriy Pyatov in the Shakhtar goal.There was no player making any form of contact with the former Liverpool man, yet the experienced Kassai pointed to the spot.“I went to chip the ball and don’t know what happened. I didn’t feel contact. I scuffed the ball. Apologies to the ref,” Sterling said after the game, according to Reuters.Shakhtar Donetsk manager, Paulo Fonseca laughed when he was asked about the decision.“It is difficult to speak about a penalty after a result like that — but it’s ridiculous, that’s all I can say,” he said.Guardiola: Sterling must ignore Ronaldo & Messi comparisons Andrew Smyth – September 13, 2019 Manchester City boss Pep Guardiola advised Raheem Sterling to ignore comparisons to Cristiano Ronaldo and Lionel Messi, who he rates as incomparable.“Everyone saw it, but it is not because of the penalty we lost the game,” he added.Meanwhile, Man City boss Pep Guardiola agreed that the referee got it wrong and said the incident highlighted the need for the video assistant referee (VAR) system to be introduced.“We realised it wasn’t a penalty. We don’t like to score in that situation,” said Guardiola, who conceded Sterling could have told the referee at the time.“You know VAR and what it is — the referee must be helped because they don’t want to make mistakes.”“The game is so quick, so fast these days. It would take 10 seconds for somebody to say something to the referee,” he added.
