Arsenal manager Arsene Wenger backed Alexis Sanchez to prove an able deputy for the injured Olivier Giroud after the Chilean forward fired his new club into the Champions League.

Sanchez scored the only goal of the game against Besiktas at the Emirates Stadium on Wednesday to earn Arsenal a 1-0 win that propelled it into the Champions League group phase for the 17th season in succession.

With Wenger revealing afterward that Giroud could be out for up to four months after undergoing surgery on a broken tibia, it was the ideal moment for Sanchez to showcase his ability to lead the line.

Asked if Sanchez could play at center forward during the period of Giroud's absence, Wenger replied: "For three or four months? He can play his whole life at center forward.

"I bought him to play striker, not to play only on the flanks."

Sanchez's goal was his first since his $50.4 million move from Barcelona but Wenger said he did not see the 25-year-old's strike as the first repayment on his hefty fee.

"I don't see it like that," said the Frenchman.

"He had a good game, not only on the technical side, but on the fighting side. He was mobile, dangerous and showed as well he has great fighting spirit; qualities that will be very important in the Premier League."

While Wenger admitted he was "open" to making new signings before the transfer window closes on Sept 1, he said that buying players was not the solution to the injuries suffered by players such as Giroud and Mikel Arteta.

"If you want to make anybody happy, you just buy all these players," said Wenger, who dismissed links with Manchester United forward Danny Welbeck, Serbian striker Nikola Zigic and former Arsenal midfielder Alex Song.

"But what's important is the performance on the football pitch and the solidarity we have shown tonight (Wednesday).

"If you look at the players we had on the bench and those who are injured, we have players. You cannot every time buy when a player's injured."

Asked if Monaco's prolific Colombian striker Radamel Falcao was within Arsenal's price range, Wenger res-ponded succinctly: "No."

Beskitas coach quiet

Wenger also praised England midfielder Jack Wilshere, who provided the spark of inspiration that led to Sanchez's goal in first-half stoppage time.

"From game to game he grows," Wenger said. "He got some critics recently and the best response is to show on the pitch that he's getting better and better.

"He has found a little burst back to get away from people, which he hadn't had for a while. In the last two, three games, you see it slowly coming back."

Wenger admitted Wilshere had been "lucky" not to concede a penalty for sliding in from behind on Ramon Motta when the score was 0-0.

Mathieu Debuchy, who was later sent off for two bookable offenses, also escaped sanction after sending Mustafa Pektemek tumbling in the box, but Besiktas coach Slaven Bilic was reluctant to discuss either incident.

The former Croatia coach watched the match from the stands after being sent off in last week's 0-0 draw in Istanbul and when asked to comment, he replied: "You know where I sat tonight.

"You aren't going to be angry if I refuse to answer those questions."
