Wenger must be a disturbed man given the Gunners' goalkeeping problems. The Arsenal first choice shot stopper has made numerous mistakes this season, costing Arsenal valuable points.
After the departure of Jens Lehmann in 2008, the 32-year-old Spaniard was entrusted the responsibility under the goal post for Arsenal. But the erratic goalkeeper has been far from impressive in fulfilling his duties.
Except his impressive penalty-saving heroics he has not done much to please either Wenger or the Gooners. The Arsenal supporters are demanding a new goalkeeper in replacement of the highly error-prone Almunia.
Almunia has been the weakest link in Arsenal's defense this season. Be it the match against Birmingham City where his silly error allowed the Blues to snatch a draw, or his wrong decision in surging forward which led to Messi's hat-trick, Almunia has seen his mistakes rob the Gunners of valuable points.
Wenger might think of selling the aging Spaniard this summer in light of the growing criticism. As Wenger looks to splash some cash this summer in order to reinforce his young Gunners, here is a look at the most eligible candidates for replacing Almunia as the new Arsenal goalkeeper come next season.
Firstly, for those who do not know the meaning of "castorino" it means "little beaver" in Italy.
Fernando Muslera, the 23-year-old Uruguayan shot stopper who plays for the Italian Serie A club Lazio, has long been on the radar of Arsenal.
The Uruguayan national team first-choice goalkeeper has been very impressive for his club Lazio. He made some decisive saves which earned him rave reviews last season.
The 6"3' glove-man was also an integral part of the club's successful campaign last season. He has been very impressive this season too.
Arsenal have been following the Uruguayan international for quite some time now and Wenger may make a move to secure the youngster's sign this summer. He may face competition from the likes of Juventus, Manchester United, and Manchester City who too have been linked with the Lazio shot stopper.
But all his suitors efforts may fail if news reports are to be believed that he has already signed a new deal with Lazio.
He could be a good choice given his young age and knowing Arsene Wenger's policy of young players he can easily fit in the bill.
These 24-year-old German goalkeeper who currently plays for German club Schalke 04 has been in top form this season. The nearly 6'5" Neuer, whose childhood idol was Jens Lehmann, has been considered by many as one of the most talented young German keepers.
His exploits under the bar for his club have earned him plaudits from all corners.
The young German has excellent positioning skills and also has a good response. Standing tall at 6'5", he is very comfortable in crosses and aerial battles. He is awesome in 1-on-1 situations. His strength also makes him a perfect fit for the Premier League's physical style of play.
But the promising youngster sometimes looks nervy during corners. He also does not catch balls quite as often as he is required to and instead resorts to punching them clear. Also, his frequent running forward from the goal is risky as the goal line becomes open and makes him vulnerable to long shots or lobs.
But he is only 24 years old and has ample scope for improvement. He can do well to solve Wenger's goalkeeping worries, which have seen his team lose valuable points in recent times.
Although Neuer has pledged his loyalty to Schalke 04, a lucrative offer along with the chance to play in one of the powerhouses of European club football may seem too good a chance for him to refute.
Arsene Wenger will have to work hard to outbid the German goalie's other two long-time suitors, Manchester United and Bayern Munich. The two clubs have long been following Neuer and looks to make moves for signing him this summer.
Although a chance to play for the team his childhood hero Lehmann played for might give Arsenal an edge in securing his sign.
Nevertheless, he can be a good bargain for Wenger this summer.
The French goalkeeper had an excellent season for Fiorentina. The 30-year-old is regarded as a world class talent similar to the likes of Cech, Buffon, and Casillas.
The French national with his amazing athleticism, brilliantly quick reflexes and good shot stopping abilities has developed into a widely respected goalie. His superb performances for Fiorentina last season earned him an extension until 2013.
But Frey sometimes makes silly mistakes in handling and is weak on corners. He also gets forced to punch frequently and sometimes looks unconvincing. But he has improved a lot this season.
Moreover, his aggression and other positive qualities helps him cope easily with his deficits.
In light of Almunia's recent mistakes and his performance coming under scrutiny Wenger looks to sign the talented Frey as a replacement for his current first-choice goalie.
With his huge experience under the goal post he can bring in immense experience to Arsenal's defense.
With news doing rounds that Manchester United are set to enter the race for signing the French goalie, as Ferguson looks to replace his veteran goalkeeper Van Der Sar, Arsenal needs to make an early move if they wish to secure Frey's sign.
The 27-year-old Scottish goalkeeper of the Black Cats has been one of the most impressive shot-stoppers in the Premier League this season.
His superb performances under the post for Sunderland against Manchester City, Birmingham, Aston Villa, and Tottenham earned him man of the match awards.
He is one of the most important reasons as to why Sunderland successfully averted a early season relegation scare. He made some decisive and incredible saves for Sunderland which saw Sunderland get clear from the relegation zone.
The 6'4" former Hearts player who signed for Sunderland in 2007 is gifted with natural shot-stopping abilities. He does a superb job in organizing the defense of Sunderland. He is also very impressive in one on one's with opponent's strikers.
Wenger is reported to be very keen in signing the Scottish national team regular. Gordon, with his experience and superb reflexes, can fit into Wenger's plans easily.
But Wenger may have to fend off stiff competition from Manchester United in his bid to sign the the impressive goalkeeper. United are looking to make a huge bid for Gordon in the summer as they try to find a replacement for the aging Van Der Sar.
