Arsenal boss Arsene Wenger insists he will not sell winger Andrey Arshavin in the January transfer window.
The Russian has rarely lived up to expectations during his three-year spell at the Emirates Stadium, having netted five goals in 2011.
Rumours have circulated concerning interest from former club Zenit St Petersburg, whom he left in 2009 to join the North Londoners for a club record £15 million in 2009, while Lazio have confirmed their interest.
But Wenger said: "On top of our injuries, we cannot lose players of that quality. It is too difficult.
"If you look at his numbers you are always surprised at how good he is. Sometimes the visual impression you get from a game has been frustrating, but he is very efficient.
"We can all have a big responsibility but we need confidence for what we do. We know he has the talent. He's been questioned many times but his attitude has always been spot on."
Reports had suggested, following Zenit's inability to agree terms with the 30-year-old, that Lazio, were ready to launch a bid, as they look to build on fourth place in Serie A.
But sporting director Igli Tare says a deal is unlikely.
"Arshavin is a great player and I think everyone would like to have him in their squad," said Tare.
"But I don't think there is any chance of seeing him in a Lazio shirt. There are a number of reasons why it would be difficult.
"We have never spoken with Arsenal and perhaps more importantly, I don't think they would want to part with a top player."
