Manager Arsene Wenger maintains Arsenal will only move in the January transfer window for the right player.

The Gunners are widely expected to strengthen this month, having already started to free-up space in the squad by off-loading Moroccan striker Marouane Chamakh on a six-month loan deal to West Ham and Swiss defender Johan Djourou to Hannover.

Wenger has been linked with a string of reinforcements from Barcelona forward David Villa, Atletico Madrid frontman Adrian Lopez, Anderlecht's Argentina midfielder Lucas Biglia, Yann M'Vila from Rennes and even former captain Thierry Henry on loan again.

He has also been repeatedly linked with a move for Saints’ teenage full back Luke Shaw.

But the Frenchman maintains he will only be tempted should a player of the required quality become available.

"We are on the market and if we find the right players, we will do something", Wenger told Arsenal Player.

Wenger is said to be keen on Villa, who was a substitute for Barcelona's 4-0 win over Espanyol at the weekend as he continues his reintegration after a spell out with a broken leg.

However, club president Sandro Rosell insists the 31-year-old, signed in a £31million deal from Valencia in 2010, is going nowhere.

Elsewhere, Sao Paulo are confident they can make Denilson's loan move into a permanent transfer, although the departure of Andrey Arshavin appears unlikely as the Russian playmaker will be drafted into first-team contention again as cover for Gervinho, who is away at the African Nations Cup with Ivory Coast.

Wenger is also determined to sign up ex-Saint Theo Walcott to a new contract sooner rather than later, with suggestions a deal, reportedly worth close to £100,000-a-week, could even be announced ahead of Sunday's clash with Manchester City.
