Szczesny has quickly become a player it's easy to expect a mistake from. That same feeling can be applied to every goalkeeper Arsenal have fielded since Jens Lehmann.
Yet Szczesny was supposed to be different. However, his habit for costly calamity—that first surfaced at Wembley in February, 2011—has frequently been evident this season.
His first appearance for the team, after suffering injury in preseason, was an ominous sign of things to come. Although Arsenal trounced Southampton 6-1, the lone goal they conceded was the fault of more cavalier play from their careless young goalkeeper.
Szczesny came for a punt into the box and the ball seemed to be easily in his grasp. He appeared to make the claim and then just as suddenly drop the ball to the floor under no pressure.
The loose ball was turned in and Arsenal had conceded their first goal in four league matches. It was not the auspicious start of a supposed star in the making at his position.
Granted, that particular blunder didn't cost Arsenal points. However, Szczesny's feeble and clumsy effort to keep out a shot against Blackburn Rovers, cost Arsenal their place in the FA Cup.
In what was his first real action, Szczesny failed to deal with a shot that came from the corner of his box. He tamely parried the effort, not to his side, or behind the goal, but straight in front of him.
It was a gift for Colin Kazim-Richards, who slotted in the rebound and knocked Arsenal, with considerable help from Szczesny, out of the cup.
Against Liverpool in January, he misjudged crosses and nearly gifted another goal after trying to execute a Cruyff turn past Daniel Sturridge.
Szczesny has simply become a player who almost promises a mistake. It's become obvious that there are two main reasons for his slapdash displays.
