Lukasz Fabianski's excellent performances in relief of Wojciech Szczesny should remind Arsenal that they need a replacement goalkeeper this summer.
Fabianski is set to leave when his contract expires at the end of the season, seeing as he has received almost no playing time this campaign due to Szczesny's excellent form.
Should he change his mind, Arsene Wenger recently told ArseBlog.com that he would be open to Fabianski remaining with the club, but the likelihood of that happening seems quite remote.
Let's look at who could replace him.
In October, Adler told Metro that he would like to play in England at some point. However, while describing it as an honor to be the subject of Arsenal's interest, he admitted he had twice turned down a move to the Gunners in his career.
While his playing time at Hamburg has been semi-regular, he would have to content himself with riding the bench almost constantly at Arsenal.
However, if Adler really loves the club and wants to move to England, he could conceivably make the switch.
He shouldn't be too expensive and would bring experience with the German national team to Arsenal's already experienced core.
This is really a long shot, but would cost Arsenal mere pennies and entails almost no risk. The soon-to-be 38-year-old is clearly nearing the end of his career. However, as his recent loan spell with Middlesbrough showed, Given still has some gas left in the proverbial tank.
He became something of a fan favorite at Boro, and though he would not be more than a bit-part player at Arsenal, his experience can't be bad to have around.
His presence has kept Adam Federici out of the starting XI, but anyone who watched the Royals' horror show of a defense in the Premier League last season knows that does not say much.
McCarthy would be a decent option to have as a backup if he is willing to become an invisible man at a relatively early stage of his career.
Remy Vercoutre would in many ways be the perfect fit for the role Arsenal are seeking.
He's played many seasons at Olympique Lyon, one of the more prestigious clubs in European football, and has been content to play the role of backup for several years in the shadows of Gregory Coupet and Hugo Lloris.
If Vercoutre was content to be second fiddle during the prime years of his career, he will probably not have a problem sitting on the bench at 33 while Wojciech Szczesny plays.
Emiliano Viviano is no doubt stewing about the fact that he is wasting his prime years on loan at Arsenal without even a place on the bench for most games.
However, the Gunners do have the option to permanently purchase him from Palermo at the end of the season, and doing so would arguably make the most sense out of any proposed move on this list.
Arsene Wenger and his staff are already familiar with Viviano and are keenly familiar with his overall quality and potential. He is already settled in at the club and in London and his purchase would require no negotiation.
When Viviano did play in Italy, he seemed to be quite a good goalkeeper. He certainly did not start 32 Serie A matches for Fiorentina last season by accident.
Perhaps next season, he'll play his first minute in Arsenal colors.
