Goaltending always seems to be the topic of conversation over at Arsenal. Despite most recognizing the signing of Petr Cech as a coup, it has continued that controversy, simultaneously creating a paradox.

The 33-year-old veteran will undoubtedly provide stability to a net that has often lacked it, but he has now created tremendous instability within the club.

With Cech's arrival, either Wojciech Szczesny or David Ospina will be leaving the Emirates. The likely candidate is the Colombian.

The irony of the situation is that Ospina actually stabilized Arsenal's net in the team's time of need. With Szczesny committing his usual gaffes, Arsene Wenger opted for giving the Colombian a go in net and Ospina not only took his chance, but ran away with it. He finished the Premier League season with eight clean sheets and looked steady and in command where Szczesny had lacked concentration.

Ospina, of course, will want to continue being a starter and some team will look at his work in 2014-15 and give him that opportunity.

Meanwhile, Cech is expected to come in and mentor the Polish netminder, who is apparently still seen as the future of Arsenal in goal. Cech likely has one or two good years left as a No. 1 and Wenger is hoping that under the former Chelsea man's tutelage, Szczesny will learn a great deal, patch up his shortcoming and become the man he has always been touted as being.

However, having Cech around essentially relegates the Pole to the bench for the majority of games. As everyone knows, a goalie who has not played is unable to build the necessary rhythm to truly be effective. Moreover, a 25-year-old goalie is about to enter his athletic prime and sitting during prime development years could be a greater disservice.

Ospina was originally acquired to be the backup, a job he willingly undertook. If Wenger really wants Szczesny to develop, he should loan him out somewhere where he will continue to accrue experience and develop. Meanwhile, Arsenal would have two dependable netminders to get it through tough competitions on the horizon.
