The Liverpool legend described the decision to award Manchester City a penalty for Marc Cucurella’s goal against Erling Haaland as “very tough”.

City took the lead midway through the first half at Stamford Bridge when Erling Haaland scored from the penalty spot.

The referee awarded a penalty after Haaland was brought down by Cucurella.

However, replays showed the two grabbing each other and it was Haaland who was the first to wrestle with the defender.

City were awarded a controversial penalty against Manchester United when Rasmus Hojlund was said to have brought down Rodri.

But Carragher said this decision is even more controversial.

During a replay of the incident, Carragher said: “That’s not right… no, no, no.” That is not true.

“The VAR seems to have reached the end of the battle.” He has to look at the beginning. This is very difficult.’

Chelsea put their problems behind them by hitting back through Thiago Silva and leveling the score for the home team.

Raheem Sterling then gave the Blues the lead when he scored against his former side to turn the match on its head.

But just before half-time, City equalized when Manuel Akanja headed past Robert Sanchez.
