Vidi and Chelsea played out a 2-2 draw in Group L of the UEFA Europa League on Thursday, with the Blues winning the group to progress in Hungary.
The Premier League side had already been confirmed as group winners before the encounter, and took the lead through Willian's free-kick after 30 minutes.
Vidi equalised immediately through Ethan Ampadu's own goal, and the hosts grabbed a shock lead as Loic Nego finished shortly before the hour mark.
Chelsea were saved by substitute Olivier Giroud with 15 minutes remaining. The Frenchman curled home a wonderful free-kick to earn a point.
