Micky Mellon was critical of his side after Tranmere's hopes of a money-spinning FA Cup 3rd Round tie were extinguished in comprehensive fashion by Leyton Orient on Saturday.

Harry Smith and Omar Beckles put the Londoners in front at the break before the rampant hosts notched two more in the second half.

Aaron Drinan scored his 11th goal of the season when he netted from the penalty spot while fellow striker Smith also reached 11 for the campaign with the fourth goal to complete the rout.

Speaking after the match, Mellon said: “We’ve let a lot of people down and our performance right from the very start was nowhere near what was required to try and get something out of the game.

“I thought we were really poor with the ball, we never passed it enough, we never fought hard enough to find the space to get on the ball and try to impact the game.

“So, overall, we were well beaten and that’s a tough thing for a manager to say.

“We have to go over the game and find out why and I’ll have a look to see what I can do to fix it.

“All I can say at the moment is that we come back in on Monday and we work hard and prepare for another game on Tuesday.

“I’m disappointed, beyond disappointed, for the performance we’ve given, it wasn’t good enough. We just weren’t at the races at all.”

Rovers boast the joint-meanest defensive record in League Two this term but they could not contain their vibrant opponents who dictated from start to finish.

The Londoners were rewarded for a totally dominant first-half performance with a two-goal lead at the interval.

They took the lead after 22 minutes when Hector Kyprianou produced a defence-splitting pass for Smith to collect before coolly sending the ball past the advancing keeper into the corner of the net.

Orient doubled their advantage after 36 minutes following a corner when Drinan pulled the ball back for Beckles to slot home.

Tranmere had been anonymous before the break and the pattern of play continued in the second period. Drinan took his tally for the season to 11 goals when he scored from the penalty spot on the hour after Peter Clarke had handled the striker’s shot.

And Smith completed the rout after 83 minutes when he stabbed home a Kyprianou cross to record his 11th goal of the campaign.

There's is little time for Rovers to lick there wounds. They are back in League Two action tomorrow evening, when they make the short journey to Boundary Park to face Oldham Athletic.

Supporters have sold out their advanced ticket allocation and will be demanding a reaction following the humbling defeat in London.
