ARSENAL manager Arsene Wenger will serve a two-match Champions League suspension after his appeal against the punishment was rejected by UEFA.
The Frenchman was initially given the suspension in the wake of the Gunners' play-off first leg at home to Udinese on August 16.
However, the club appealed and the sanction was postponed but European football's governing body have reinstated it after turning down the appeal.
Arsenal were also fined €10,000 (£8,700) for improper conduct of their officials.
Wenger was punished after being caught relaying messages by telephone to the bench from his seat in the stands where he was serving a ban carried over from last season.
"The UEFA Appeals Body has rejected the appeal lodged by Arsenal FC and Arsene 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," said a statement from UEFA.
Wenger will now be forced to sit in the stands for Arsenal's first two group games in the Champions League -- away to Borussia Dortmund and home to Olympiacos.
