Formed - 1951.
Nickname - The Horsemen.
History in the making - This is the first UEFA club meeting between teams from England and Azerbaijan. However, Qarabag have visited the UK twice before - they beat Portadown of Northern Ireland in Europa League qualifying in 2010 and took on Celtic in Champions League qualifying this season, losing 1-0 over two legs.
Four Lions - Five of our former players have played against Azerbaijan - Sol Campbell, Jermain Defoe, Jermaine Jenas and Paul Robinson all started England's World Cup qualifying win in Baku on October 13, 2004. Robbo then started the home match - a 2-0 win at St James' Park on March 30, 2005 - Ledley King came off the bench in that game, alongside Jermain.
Form - Qarabag have already played 10 matches in all competitions this season, and they've only lost once, 1-0 against Celtic in the Champions League qualifier at Celtic Park. They've won five on the trot in all competitions.
European form - Qarabag beat Young Boys over two legs to qualify for the Europa League group stages. They have won three of their last five European away games - including a fine win against last season's eventual runners-up Dnipro in the group stages last season.
Domestic form - Qarabag top the table again with three wins and a draw from their four games so far.
Last time out - Qarabag beat Xazar Lankaran 1-0 in the league thanks to Samuel Armenteros' 73rd-minute goal.
Home sweet home - We've lost only one of our last 17 home matches in Europe - a 3-1 loss against Benfica in 2014.
Air miles - It's approximately 4,000 miles from Baku to London - the longest trip on Matchday One.
Champions - Qarabag are one of 10 domestic champions in the Europa League group stages. They've won the Azerbaijan title on three occasions.
We've met before - Qarabag midfielder Michel came off the bench for Birmingham City in a 1-1 draw at St Andrews in the Premier League in December, 2010.
About the coach - Gurban Gurbanov tops the Azerbaijan international goalscoring charts with 12 goals in 62 caps. He has been coach at Qarabag since 2008 and led the team to successive titles.
