Arsene Wenger has attempted to steer around speculation linking him with a move for Gary Cahill.
The Arsenal boss is known to be in the market for a centre-half, with Thomas Vermaelen and Sebastien Squillaci currently sidelined.
Bolton man Cahill was believed to be top of his January wish list, with the England international having been touted as a possible new recruit for some time.
The arrival of David Wheater at the Trotters this week has only served to fuel those rumours, with many taking Owen Coyle's swoop for defensive cover as a signal that a sale could soon be on its way.
It is, however, expected to take some £10million to lure Cahill away from the Reebok Stadium, and Wenger is notoriously cautious when it comes to splashing the cash.
The Frenchman has refused to confirm whether the former Aston Villa man is in his thoughts during the current transfer window, but has also stopped short of completely ruling himself out of the running.
"At the moment, I cannot come out with any name," he said.
"I think Gary Cahill is a very good player, but I cannot tell you more.
"We like to keep our transfer negotiations always very secret, because it puts more pressure on when you go public so you would understand we don't want to speak publicly about that."
Wenger admits a new centre-half would not go amiss over the coming weeks, but insists he has the strength in depth within his squad to handle the current injury dilemma should his pursuit of fresh faces prove fruitless.
"It is a worry as long as [Sebastien] Squillaci is out, I must say, as we are short, but we have other resources," he said.
"If the worst came to the worst, [Abou] Diaby is coming back so if we have to put [Alex] Song back we have Diaby coming back to play in midfield."
