Aaron Ramsey believes Arsenal can use the 3-0 win over West Ham as a template to produce the same result in Monaco next week and keep their Champions League hopes alive . The Gunners eventually saw off the challenge of the Irons , who suffered a third straight Barclays Premier League defeat , to move within a point of second-placed Manchester City with what was a eighth win out of the last nine . There is , however , little time for Arsene Wenger 's men to recover before they must again raise themselves for the trip to Monaco and the quest to overturn a 3-1 first-leg deficit which has left their Europeans dreams hanging by a thread .

Ramsey , who scored Arsenal 's second goal on 84 minutes before substitute Mathieu Flamini tapped in a third moments after coming on , feels a similar positive approach can see them pull of an unlikely result at the Stade Louis II Stadium . 'We will go there and try to score three or more goals and hopefully not concede any , that is our target and is how we will approach it , ' the Welshman said . 'We had a sloppy first leg and we have made it quite difficult for ourselves , but it is not over yet . Olivier Giroud has rediscovered his goal scoring form after missing chances against Monaco . Arsenal manager Arsene Wenger watches on knowing his side will face a stiffer test in Europe . 'We are more than capable of scoring three goals . We scored three on Saturday and we believe in ourselves . 'So we will go into the game believing we can achieve that . ' After seeing Theo Walcott , recalled into the starting XI for the injured Alex Oxlade-Chamberlain , thwarted by some good reactions from West Ham goalkeeper Adrian - who played despite suffering a dislocated finger in the warm-up - Olivier Giroud eventually fired Arsenal into the lead on the stroke of half-time with a fierce left-footed shot drilled in off the far post . West Ham raised their game for the second half , but were unable to convert that dominance into a goal . Alexis Sanchez looks dejected as Monaco tie up a 3-1 first leg lead at the Emirates .

Sam Allardyce opted out of his post-match media duties to try to lift the squad , who have seen solid performances against the likes of Manchester United , Tottenham and Chelsea fail to earn a victory . Midfielder Mark Noble is confident the eight-match winless run will soon be ended , as the Irons look to get some of their walking wounded back into the squad ahead of the home game against Sunderland . 'We have been through a tough patch after a great first half or the season , so we need to kick on now for the last quarter of it , ' Noble said . 'We have got a good bunch of lads and will keep working hard , training well and hopefully we can get some points against Sunderland next week . '
