Ancelotti said: "It will be an attractive football match, each team has its own characteristics, both with a lot of quality. This quality is going to make for a very nice match at a technical level.
"We think of being superior in some aspects, they in others. The superiority will be seen at the end of the 180 minutes, when we see who wins the tie.
Guardiola is a great coach, period. It doesn't bother me what they think of me, I care what they think of my club."
On Jude Bellingham, he added: "He is a great player to appear in the area at the right time. Physically he is very strong to cover a lot of field and to contribute a lot in defence. He creates spaces and opportunities for us.
"The key is that he is very mature, despite being 20 years old. He is very professional and humble, he does not surprise us as a player, but as a person he does. He is very mature."
