The Gunners threw away a 2-0 half-time lead during Saturday's north London derby at Emirates Stadium, where victory would have sent them top of the Premier League. Manager Arsene Wenger lamented the inability of his young side to deliver a big performance when it mattered most as they suffered a second successive home defeat. Chamakh - who took his tally to nine goals with a close-range effort - feels having facing Braga so quickly is the perfect opportunity to put that disappointment behind them. "It will help us to forget the Tottenham game and we must focus on Braga and get a victory," the Moroccan said. Arsenal remain top of Group H, despite losing their last European fixture away to Shakhtar Donetsk - another match in which they were well in control. Braga were thrashed 6-0 at the Emirates Stadium on Matchday 1 during September, but could put themselves right back in contention for qualification to the last 16 with victory over the Gunners. Chamakh knows there can be no complacency against the Champions League new-boys. "The group is tight," he said. "There are three teams going for top spot so we know we need to get a win over there." Wenger had lambasted his side for being complacent when leading against Shakhtar through Theo Walcott's early breakaway goal, and it was a trait which appeared to have resurfaced against Spurs. The Arsenal manager will leave his squad fully aware of the need to maintain 100% focus in Portugal. "It is very important that we do not repeat the performance in Donetsk," he said. "We need to produce a performance that allows us to get the points to qualify, but I also want to win the game as that gives us the possibility to finish the group stages very strongly, that is our target - we are ambitious to win the group." Midfielder Jack Wilshere should be involved having been left on the bench against Spurs following the back problem which kept him out of England duty. Denmark striker Nicklas Bendtner was again conspicuous by his absence from the match-day squad, having publicly questioned Wenger's selection policy, but is likely to be in the group which heads off from Luton later this afternoon. Veteran goalkeeper Manuel Almunia may also be ready for a recall, having been sidelined since the end of September with an elbow injury.
