Arsene Wenger has confirmed that Arsenal are set to discipline goalkeeper Wojciech Szczesny after he appeared to make an obscene gesture following his sending off in Wednesday's Champions League clash against Bayern Munich, reports fourfourtwo.com.
The Poland international let his frustration boil over after seeing red in the first half of this week's last-16 first leg tie, after bringing down Arjen Robben in the box and denying him a clear goalscoring opportunity.
Szczesny will be suspended for the return leg at the Allianz Arena, with Lukasz Fabianski set to deputise, but the Gunners number one could face a further ban from UEFA if they decide to review the incident.
"It was frustration but we are professionals, me included, and we have always to master our reactions," reflected Wenger. "Wojciech is part of that as well.
"We'll deal with that internally. We don't agree with that."
The 23-year-old will be available for Arsenal's Premier League match against Sunderland at the Emirates Stadium on Saturday, and will have to wait and see if his actions prompt a further European punishment.
Either way, Szczesny will not avoid an internal disciplinary, with Wenger keen to avoid any repeat of the unsavoury scenes on show on Wednesday.
