PSG sporting director Leonardo described the club's opponents as 'very difficult' in the Champions League. Leonardo: "I think Leipzig are showing every year that they are better and better. I think that our group is very difficult. We are with Manchester United, who are back in the Champions League. They have new players. They are a young team but a very strong team. Leipzig reached the semi-finals last season in the Champions League. And [Istanbul] Başakşehir won the Turkish league. So I think we are in a very difficult group."
