Lampard is weighing up a significant gamble over whether to include Antonio Rudiger for only his second appearance since April 28 in Chelsea's crucial Champions League showdown against Lille.
Team News
Rudiger is expected to make his comeback from injury imminently and could even be thrust into the team here with Tomori injured.
Jorginho has started Chelsea's last two games on the bench but will surely return to the fold here with Chelsea requiring a positive result to go through. Mount may drop to the bench as a result.
Both Azpilicueta and Jorginho are one booking away from a one-match ban in the Champions League.
Focus
Chelsea will go through if they beat Lille, or if they draw and Valencia lose to Ajax. Chelsea have lost three of their last four, hitting bad form at the worst moment.
Lille are guaranteed to finish fourth regardless of Tuesday's result. Lille have won their last three matches by 1-0 scorelines. They won their first away game of the season last time out on the road.
As Lille have nothing to play for, the situation could not be more perfect for Chelsea to go out and get the result they need to qualify. It would be a disaster if they crash out of the Champions League.
Probable Line-ups
Predicted Result
Chelsea 2-1 Lille
