After losing their opening Group I fixture to Atletico Madrid 2-0 in Spain earlier in the month, Ki is looking for Celtic Park to inspire the players in the games against the Spanish club and Rennes, following this week's visit of Italian outfit Udinese.
"We have just played one game and if we win against Udinese we still have a chance," said the 22-year-old South Korea international.
"We will have to be at our best and if we get a chance we will have to score.
"Away games in the Europa League or Champions League are not easy so we should at least draw away games and win every home game, that is our target.
"But as I said, it's not going to be an easy game because they are a good team.
"They are doing very well in Italy but it is our home game which means we have a lot of fans behind us.
"So we want to win the game."
