Chelsea might face a difficult Champions League round of 16 encounter after finishing second in Group H.
Zenit held the Blues to a 3-3 draw in Russia on Wednesday night.
Thomas Tuchel’s side took the lead through Timo Werner but fell behind to goals from Claudinho and Sardar Azmoun.
After the interval, Chelsea’s Romelu Lukaku equalized before Werner put them back in ahead.
However, the Blues conceded a late equalizer scored by Magomed Ozdoev.
Juventus have won the group, thanks to a 1-0 win over Malmo.
Chelsea will not be paired against Juve but they can face non-English clubs who topped their groups.
That includes Real Madrid, Bayern Munich and Ajax.
