The players arsenal need to buy:Part 1(GK)

In my last post i asked arsenal fans who they would like to see in an Arsenal shirt,in this post i will give my opinion on who i think we should sign.The positions that Arsenal need to strengthen are Gk,Cb,Dm and St,i would also prefer a winger if wenger decides to sell gervinho.

GOALKEEPER
JULIO CESAR

Reports are that Arsenal have agreed a preliminary contract with julio cesar of qpr but both parties are looking at other options available to them and it is said that wenger is not really convinced about cesar but if he could not find a better gk than the deal will go through.

Pros:He is at an age where he would offer competition to szczesny but not push him out the team,he has a lot of experience of playing at the highest level and winning trophies,his experience could help the youngsters especially szczesny.
Cons:Cesar would not be my first choice either he was a great gk at Inter but there is a reason that Inter let him will leave he is not the the same player anymore and is especially weak at handling crosses which is one of the main attribute required to be a gk in Epl
Probability of transfer:8/10

RENE ADLER

The Gk i would like to see at Arsenal is Rene Adler,the only reason he is not Germany's no 1 right now is because of an unfortunate injury he suffered before the world cup in africa.Adler's links to Arsenal were hot in May but have cooled down now even though he admitted recently that he would like to play for a club like Arsenal
Pros:He is strong at handling crosses,commands his box well and is entering the prime of his career.Adler would not be very expensive leaving more money for other positions and has performed consistently this season for Hamburg fighting his way back into the German national side after receiving a call up last year.
Cons:The only thing against adler that i can think of is that he could push szczesny out for the long term which would eventually result in szczesny's departure who is a passionate Arsenal fan and a fan favorite.
Probability of transfer:3/10
