Graham Poll claims Lucas SHOULD have been sent off against Chelsea, plus his views on Costa v Skrtel

Mourinho aimed a thinly veiled criticism at Mark Clattenburg as he - with the scores locked at 1-1 - decided against handing the Brazilian a second yellow card after what looked like a clear foul on Ramires.

Liverpool went on to secure a 3-1 win at Stamford Bridge to pile even more pressure on the Blues boss, but Poll believes Chelsea were potentially robbed of points because of the poor decision.

“I have to say I think Mourinho was right,” he told Hawksbee and Jacobs

“You can’t expect a referee to be 100 per cent correct all the time – like players and managers, they are human – but what you do expect is consistency in the 90 minutes.

“Now, on Saturday, Mikel was cautioned and very soon afterwards Lucas goes in.

“He knows he isn’t getting the ball and he’s that kind of player, he knows what he’s doing, he’s a clever player and I thought from his body language that he expected to be sent off.

“And I couldn’t understand it - it was a clear and obvious yellow card for anyone who was watching the game.

“For me that was a big incident. Chelsea may well have lost anyway, but at 1-1, with Liverpool reduced to ten men away from home, you would have expected Liverpool to hold on for the draw at that point.”

Another incident in the heated game saw Chelsea stirker Diego Costa and Liverpool centre-back Martin Skrtel resume their on-pitch rivaly.

The duo have history, with Costa handed a ban after being found guilty of stamping on the Slovakian last season, and it appeared the Spaniard was fortunate to escape punishment once more after replays showed he kicked out at the Reds defender again on Saturday’s lunchtime game.

Skrtel managed to keep his cool and it was confirmed on Monday that the FA would be taking no action over the incident.

And Poll was pleased with the outcome, saying that those physical battles are a part of the soul of the game.

“I was really glad to read that no action was going to taken out on Diego Costa,” the ex-official added.

“He is a combative player, but so is Martin Skrtel. They decided they’d have a good battle together on Saturday and didn’t moan too much about it.

“It was good to see Costa getting stuck in and not bleating too much. He got a bit of a firearm smash earlier in the game, and he gave a little bit back.

“As a spectator you like to see those battles, that’s how it should be. As a referee, if two players - a big [number] nine and five – want to have a good battle and keep it between themselves and it’s reasonable, then let them get on with it.

“It’s how they want to play the game and it’s how the game should be played."
