Everton manager Roberto Martinez has described his side's 4-0 defeat to Liverpool in this evening's Merseyside derby as a "disaster" and an "embarrassment".

The Toffees conceded two goals late in the first half before Ramiro Funes Mori was shown a straight red card five minutes after the restart, leaving Liverpool to take complete control at Anfield.

Daniel Sturridge and Philippe Coutinho capped off the scoring on a miserable night for Everton, but Martinez urged his side to bounce back when they face Manchester United in the semi-finals of the FA Cup on Saturday.

"It was a disaster. A horrible showing that started with the best intentions but ended up with the inability to get the basics right. We forgot to defend the box and gave them a soft two-goal lead. We got emotional with the red card and from then on Gareth Barry was injured and John Stones was ill, it was a chain reaction. A disaster. An impossible experience," he told Sky Sports News.

"It is a challenge that [Funes Mori] should avoid. He got carried away with the emotion of a derby, he got carried away. Probably a red card, I can understand it or maybe a yellow. The top and bottom is that we didn't cope with the emotions of the occasion. A feeling of embarrassment.

"It is a huge game for us on Saturday in the FA Cup which is the only good thing. We will be hurting for a long, long time but we need to react quickly for the game on Saturday. We are strong enough to react but we are short at centre-back now."

Everton are now winless in their last seven Premier League matches and their last 11 Merseyside derbies in the top flight.
