London - David Ospina insists Arsenal's Champions League shock at the hands of Monaco is now behind them ahead of their visit to struggling QPR on Wednesday.
Arsene Wenger's side responded positively to their devastating 3-1 Champions League last 16 first leg defeat against Monaco by beating Everton 2-0 at the Emirates Stadium on Sunday.
The victory helped draw a line under a loss that means the Gunners go into the second leg tie in Monaco knowing their prospects of reaching the quarter-finals are slim.
Instead, Arsenal's best prospects of success this season now lies in ensuring they achieve a top four finish in the Premier League and advance in the FA Cup.
Manchester City's weekend defeat at Liverpool means Wenger's men have progressed to within four points of Manuel Pellegrini's second-placed side and will maintain the pressure on the champions if they can claim three points at Loftus Road.
Chris Ramsey's side are battling for their Premier League survival and Arsenal will start clear favourites to return to north London having secured a seventh win in eight league games.
Ospina, the Gunners goalkeeper, is confident Arsenal's shaken belief has been restored by the win over Everton and they can now look forward to the closing weeks of the season.
"We were not nervous, we were sad after the Monaco result but in football you have to pick yourselves up quickly," he said.
"Obviously it was a tough night but you have always got to bounce back and Everton was a great way to show that we had done that.
"After what happened against Monaco, the only thing that was important was to win the big game to continue increasing our confidence and keeping heading up the table.
"Now we are already thinking about the next one, which is QPR."
The prospect of challenging City for second place is another incentive but Ospina insists nobody at the Emirates Stadium is looking too far ahead.
"We know we are close to them now but we need to concentrate on ourselves and not think about them. We will keep doing our job, picking up points and then see what happens," he added.
