Arsenal have failed in their bid to have Arsene Wenger's two-game suspension from Uefa overturned.
The governing body handed Wenger the ban for remaining in contact with his coaching staff during Arsenal's Champions League qualifier against Udinese at the Emirates Stadium while serving a one-match suspension.
"The UEFA Appeals Body has rejected the appeal lodged by Arsenal FC and Arsène Wenger against the two-match suspension handed to the manager," read a statement on Uefa's official website.
"The Control and Disciplinary Body also fined Arsenal €10,000 for improper conduct by their officials during the match against the Italian team."
Wenger will now be absent from the Gunners' opening group matches against Borussia Dortmund and Olympiacos.
