The Russian international fits perfectly into Arsene Wenger's mould - under-rated, relatively unknown, and with maturity beyond his years.

Although the 24-year-old has begun to receive rave reviews this season in CSKA's run to the Champions League quarter-finals - and he is a bigger name after starring in Euro 2008 - he is still not considered among the elite.

A move to the Emirates Stadium would catapult him into the spotlight, but Wenger can rest easy that the relative youngster can handle it - he made his international debut at 18 and was installed as CSKA captain at just 21.

Current Gunners star Andrei Arshavin, who is adjusting well to life in London, is also sure to put in a word for Arsenal with his Russian international team-mate.

Hart has no immediate future at Champions League-chasing Manchester City, with Shay Given still proving he is among the world's best goalkeepers as Roberto Mancini's first choice.

The England hopeful has impressed during his season-long loan spell at Birmingham City, to such an extent that Alex McLeish is desperate to turn his move into a permanent switch.

However, Hart may find it difficult to turn down a move to Arsenal - which would not only give him Champions League experience and a realistic shot at domestic and European honours, but he would also put himself into pole position to become Fabio Capello's first choice number one with England.

Green's availability this summer will surely depend on West Ham's Premier League fate, which still hangs in the balance.

Go down, and the England international will definitely move on - probably for a cut-price fee. Stay up, and he could stay at Upton Park - provided he renegotiates his costly contract.

With Arsenal's strict wage structure, Green would not be looking at a bumper pay day but given the chance to challenge at the sharp end of every competition he would likely forgo opportunities elsewhere.

Doubts still linger over his pedigree as a top-class goalkeeper but in terms of available options in the Premier League, there are few better.

It's Arsenal's worst-kept secret that Arsene Wenger is a big admirer of his countryman Hugo Lloris - a 23-year-old talent who promises to be one of the forerunners for a new generation of European goalkeepers.

Having usurped Steve Mandanda as France's first-choice shot-stopper for this summer's World Cup, Lloris has earned plaudits for his performances in the Champions League and at international level.

And having put in two excellent displays against Republic of Ireland in the two-legged World Cup qualifying playoffs last year, Lloris is fast becoming a well-known name on these shores.

He has already been linked with the likes of Tottenham and Manchester United, but Arsenal is a known breeding ground for young French talent in the Premier League - immediately putting Wenger at the front of the queue for his signature.

If Wenger decides against a move for Green or Hart, or simply gets scuppered in his attempts to sign either, but still wants someone with Premier League experience there are still other options on home soil.

Chief among them is Wigan's experienced stopper Chris Kirkland, who still harbours slim hopes of going to this summer's World Cup with England.

Kirkland is certainly a capable goalkeeper and, at 28, still has his best years ahead of him.

However, with Arsenal's injury problems this season fans would question the wisdom of signing a player with such a well-documented history of fitness issues.
