It is top against bottom on matchday three when FC Barcelona welcome Olympiacos FC to the Camp Nou with six points already separating the sides in Group D.

• While Ernesto Valverde's current team have won their first two games, scoring four goals and conceding none, Olympiacos are still without a point and could have their work cut out to get off the mark in their first encounter with Barcelona.

• The match pits Valverde against one of his former clubs, the Barcelona coach having won three league titles in two spells at Olympiacos.

Match background

Barcelona
• The Blaugrana have won nine of their 12 fixtures against Greek opponents, losing two. They have won all six home games, scoring 26 goals and conceding three.

• Barça have won their last three matches against teams from Greece, all against Panathinaikos FC, including home (5-1) and away (3-0) victories in the 2010/11 group stage. Lionel Messi got three of those goals and was also on target in the 5-0 thrashing of the Greens in 2005/06.

• The Spanish side are unbeaten in their last seven meetings with Greek opposition, home and away, winning six.

• This is Barcelona's record-equalling 22nd UEFA Champions League group stage campaign, and 14th in succession. They last failed to reach the last 16 in 2000/01, although they did not take part in 2003/04.

• The Blaugrana last failed to progress beyond the round of 16 in 2006/07; their last two campaigns have been ended in the quarter-finals, by Juventus last season and by Club Atlético de Madrid in 2015/16.

• The 0-0 draw with Juve in last term's quarter-final second leg was the only time former Barcelona coach Luis Enrique failed to win a home game in the UEFA Champions League, having previously mustered 15 straight victories.

• Barcelona are unbeaten in 22 matches at home in the competition, a run that started in September 2013 (W20 D2); they were 3-0 victors against Juventus on matchday one.

Olympiacos
• The Thrylos have never won in Spain, where their record reads W0 D2 L12.

• They have been beaten on their last five trips to Liga teams, most recently going down 4-0 at Atlético in the 2014/15 group stage; they last avoided defeat in Spain when holding RC Deportivo La Coruña 0-0 in the 2004/05 UEFA Champions League group stage.

• Olympiacos succumbed 2-0 at Juventus on matchday two, but have won three of their last five European away games, including the first two this season. In their last UEFA Champions League group campaign, in 2015/16, they won two of their three away fixtures.

• Olympiacos opened this season with a 5-3 aggregate success over FK Partizan in the third qualifying round (3-1 away, 2-2 home). They then got the better of HNK Rijeka in the play-offs, coming through 2-1 at home and 1-0 away.

• Olympiacos are in the group stage for an 18th time. They lost to Hapoel Beer-Sheva FC in last season's third qualifying round, the first time they had missed out on the UEFA Champions League group stage since 2010/11.

• In 2016/17, the Greek side went on to make the UEFA Europa League round of 16, falling 5-2 on aggregate to Beşiktaş JK.

• The Piraeus club earned a place in this season's qualifying rounds by lifting their 44th Greek championship in 2016/17 – their seventh in a row.
