Arsene Wenger says Laurent Koscielny is a shining example of Arsenal's ability to turn relative unknowns into big names.

The France defender had spent just one season in Ligue 1 when he left Lorient for Emirates Stadium in the summer of 2010 but Koscielny has since developed into one of the stand-out performers in Wenger's team.

The 27-year-old has yet to misplace a pass in his two appearances this season and that doesn't surprise Wenger.

"He's a footballer of course," the manager told Arsenal Player. "That's what our fans understand as well.

"He's just another example of the trust we have in players when we bring them in. It was not a spectacular signing at the start but who would deny it today?

"That's why I'm absolutely sometimes surprised, with all the examples of players that have come here unknown and become great players, that the demand is just on getting big names. It's important, big names, but there's as well room for good players."

Big names or otherwise, Wenger expects to be busy in the transfer market before the deadline passes on September 2. He believes any new recruits will help an already talented squad kick on.

"Things will happen. I am not anxious about the situation," he said, adding that Arsenal's results in Europe are cause for optimism.

"We lost against Bayern last year on [away goals] and they won the European Cup. We won at Bayern 2-0. We won at Fenerbahce 3-0. You can analyse all the results in the Champions League and you don't see that often. I think it's time we realised that.

"Of course we're all sorry for what happened on Saturday [against Aston Villa] but [it's important] we all get behind the team and we show what has always been the strength at this Club - to be together, support the team and [appreciate] the players we have and not always dream of players who are outside everywhere.

"We have fantastic players and it's time we understand that."
