The Champions League Round of 16 of February 2011 brought the most recent reunion, former Chelsea winger Jesper Gronkjaer was then part of Copenhagen’s side. Goals in either half from Nicolas Anelka put Carlo Ancelotti’s team in charge and the second leg at the Bridge finished 0-0.

Chelsea scored 26 goals in the previous stage – more than three times the Lions’ share – and conceded five compared to the Danes’ nine.

Christopher Nkunku has had a hand in eight goals in five games in this competition (proper) to date (five goals, three assists). He also scored in both of the qualifying round matches against Servette.

Marc Guiu, who misses out tonight through injury, is the competition’s joint leading marksman with six goals and has recorded the most shots on target (12).

Chelsea’s first ever competitive fixture in European competitions was away to Frem of Copenhagen in the 1958/59 Inter-Cities Fairs Cup, a 3-1 win.

The Blues’ 1-0 win at Copenhagen on 5 November 1998 was the first time the club fielded a full team plus substitutes who were all full internationals.

Only five players in this season’s competition have regained possession of the ball more than FCK centre-back Gabriel Pereira.

Chelsea have not lost a game in March in any competition for nearly six years, winning 18 and drawing four since a loss at Goodison Park on 17 March 2019.

The Blues are targeting a club record seventh successive win in European competition – the current run of six equalled our 2018/19 Europa League spree.
