Arsenal are on a high, and Petit believes they should thank AC Milan for it.

Arsenal v Olympiakos
Group F, Match Day 2
Emirates Stadium
20:24 CET (19:45 Local Time)

Arsenal head into their first home game of the 2011/12 UEFA Champions League in some indifferent form but Arsene Wenger will be hoping their victory over Bolton on Saturday will kick start their season and Arsenal will head into their clash with Olympiakos in confident mood.

Arsenal met Olympiakos in the 2009/10 Champions League group stage and defeated the Greek side 2-0 at home but was defeated 1-0 in Greece. Arsenal has played six times against Greek opposition in the Champions League, winning four, drawing two and remains undefeated.

Olympiakos have failed to win any of their nine away games in the Champions League against English opposition, losing all nine and conceding 29 goals along the way. Last season, Arsenal scored 14 home goals in the Champions League group stages and defeated Braga 6-0 in their first home match of the 2010/11 Champions League campaign.

If Arsenal scores this evening, it will be their two-hundredth goal in the competition.
