Morais enjoyed a spell at Stamford Bridge while Jose Mourinho was in charge at the club, but never won a medal with the club.
He said: “It’ll be a different experience for me playing against my former club, but we must treat it as just another game as much as we can.
“It’ll be one more game. I will do my best for the team. I want to prove something to them, of course. If we can show our quality in the Champions League, maybe it will open doors for some of our players.
“I enjoyed my time there but I don’t have any medals from those days.
“I played some games in the Premier League but, in England, they only give you medals if you play a certain number of games. I did not qualify for a medal.”
