Arsène Wenger expects to welcome a new defender to Arsenal "quite soon".

The manager has been linked with a number of centre backs this summer as William Gallas, Sol Campbell and Mikael Silvestre all approach the end of their current contracts at Emirates Stadium.

Wenger told Arsenal.com last week that he wanted to announce a new signing before the end of the World Cup but he is staying tight-lipped over the identity of that player amid reports that Lorient defender Laurent Koscielny is close to completing a move to North London.

"Nothing has been done yet but I expect something will be done quite soon on that front, on the defensive front. We will sign a player soon," Wenger told Arsenal.com this week.

"But we do not want to come out with names before we announce it.

"Keep faith in what has always worked well for us and that is to keep it secret as much as we can."
