We take on the Serie A giants at the famous Stadio Artemio Franchi with the aggregate score of the tie poised at 1-1 after last week's first leg at the Lane.
Speaking ahead of training on Wednesday night, Mauricio told us: "Yes, everyone is fit and now we need to decide the squad for tomorrow night. Some players have stayed in London and now we need to analyse and decide the best side."
Brad Friedel, Younes Kaboul, Etienne Capoue, Cristian Ceballos, DeAndre Yedlin and Emmanuel Adebayor have remained at the Training Centre.
We kick-off tomorrow at 6pm UK time.
