Arsenal made their disastrous Carling Cup loss a distant memory with a 5-0 hammering of league one side Leyton Orient in the FA Cup fifth-round replay at the Emirates Stadium. 

Nicklas Bendter's hat-trick was sandwiched by Marouane Chamakh's 7th minute opener and Gael Clichy's 75th minute strike. The win ensured that Arsenal will face Manchester United in an enticing quarter-final draw.

After having lost the chance to end their trophy drought with a horror loss against Birmingham City in the Carling Cup, many expected the young Arsenal side to falter. However, the second-string side started off in determined mood and Maroune Chamakh slotted in the opener in the 7th minute.

It was Bendtner show from there on, grabbing his first with a well-taken header before doubling his tally with a curling finish.It gave Arsenal a 3-0 lead going into half-time.

Arsenal started the second half the way they had ended the first and the continuous pressure saw Orient's Alex Revell trip Kieron Gibbs in the box, just past the hour mark for a penalty. Bendtner calmly strolled it in to cap an incredible performance. However, it wasn't over yet as substitute Gael Clichy's low drive in the 75th minute gave Arsenal the boost they needed after their Carling Cup catastrophe. 

After the game, Arsenal boss Arsene Wenger, said, It was a good response. We took the game in a serious way and we didn't release the pressure. We kept the ball well and we're on a fantastic run, except for Sunday, so we're quite positive. Conor Henderson did well, all the young boys did, Miquel as well. Henderson is a good player and wasn't phased. You cannot afford injuries, so for Nicklas Bendtner and Marouane Chamakh to score was important for us. Marouane was lacking confidence, but he's coming back, so the goal has meaning for him. Tomas Rosicky has a little concussion for an accidental elbow but he'll be OK.
