The Polish shot-stopper has been commanding in the Gunners’ last two victories and Wenger feels he is now making his presence felt, especially with the aerial balls.
"He comes off the line much more to claim the ball," Wenger observed to the club's official website.
"His movement to take the ball at the peak is much better and he has shown that, especially in the last two games against Swansea and Napoli, when it was needed to come off the line and take a cross.
"It sometimes has a psychological impact on an opposing team when a goalkeeper comes to claim a cross or is quick off his line."
