The following has been announced by UEFA:
"The UEFA Appeals Body has rejected the appeal lodged by Arsenal FC and Arsène Wenger against the two-match suspension handed to the manager in the wake of the English club's UEFA Champions League play-off first leg against Udinese Calcio on 16 August.
"Wenger will now be suspended from carrying out his duties at Arsenal's next two UEFA competition matches – the UEFA Champions League group stage games against Borussia Dortmund and Olympiacos FC on 13 and 28 September – in accordance with the decision taken by the UEFA Control and Disciplinary Body on 22 August.
"The manager was awarded this suspension for not abiding by an earlier decision of the Control and Disciplinary Body during the Udinese home game – in which Wenger was serving a one-match ban imposed following Arsenal's final UEFA Champions League game of last season.
"The Control and Disciplinary Body also fined Arsenal €10,000 for improper conduct by their officials during the match against the Italian team in north London."Copyright 2015 The Arsenal Football Club plc.
