UEFA has banned Arsene Wenger for three matches for improper conduct in relation to comments he made about the match referee after Arsenal's Champions League game against AC Milan on 6th March.
As well as being suspended from carrying out his managerial duties for the team's next three European games, Wenger has been hit with a fine of €40,000 (£33,000).
It is the third time the Frenchman has been given a touchline ban in the space of a year and, barring an appeal, will be a blow for the club when they return to continental competition.
Arsenal are currently on course to qualify for next season's Champions League after moving into third place in the Premier League on the back of a seven-match winning run.
UEFA had previously handed Wenger a one-match touchline ban for an on-field rant at Massimo Busacca following his team's last-16 exit to Barcelona last year.
The Arsenal boss was left fuming at the Swiss referee's decision to send off Robin van Persie.
Wenger was then handed a further two-match touchline suspension for violating his Barcelona ban by communicating with the Arsenal bench from the stands during the Gunners' play-off tie against Udineseearlier this term.
His latest UEFA charge came after he criticised Slovenian official Damir Skomina for his performance in the second leg of this season's last-16 tie against Milan.
The Gunners won the match at Emirates Stadium 3-0 but were knocked out 4-3 on aggregate and Wenger felt Skomina had awarded too many decisions to the Italian visitors.
He said at the time: "I was not happy with the referee tonight because I felt he gave many free-kicks in the middle of the park.
"Every time they went down a free-kick was given for them, and they sensed that very quickly and they used it very well."
