Former Premier League ref Graham Poll says Liverpool's third penalty was legitimate.
Danny Sturridge appeared to dive for the spotkick, which also saw Nemanja Vidic sent off by ref Mark Clattenburg.
But Poll wrote in the Daily Mail: "The third Liverpool penalty and the least clear as Vidic slides across the path of Daniel Sturridge but misses the ball. He does not actually trip the striker but still impedes his progress and the penalty is correct.
"This time Clattenburg does show the yellow and as it's his second Vidic is also shown the red card - it is extremely harsh on the Serb as it is a careless challenge and the decision is completely inconsistent with the earlier ones."
