It will be the first time he's played against team from his own country.
"It is an important match and obviously our objective is to qualify, though we certainly won't say that after winning the first leg 2-0 the tie is all over," said Chivu.
"I am ready to play, but only after today's training session will we know if I'm 100 per cent fit. Cluj are a good side, which was clear in the Champions League, so we are not underestimating them.
"It's my first game against a Romanian side, so I am a little emotional. This is a special game for me," he confessed.
