Napoli coach Walter Mazzarri claims that Manchester City are already at the level of Barcelona and Real Madrid, but has urged his side to play without fear in the Champions League clash on Tuesday.
City, the impressive leaders of the Premier League, can secure a place in the last-16 of Europe's elite competition with victory at Napoli and Mazzarri is aware that his opponents have a top qualify side.
"They are in a great period of form, but we have to play without fear," he said. "No matter who they put on the field, they have the same strength as Barcelona or Real Madrid.
"City are doing well in their championship - they scored six goals at [Manchester] United - but we have the weapons to hurt them."
Meanwhile, City playmaker David Silva is aiming to win the trophy this season despite it being the club's debut campaign.
The Spaniard told UEFA's 'Champions' magazine: ''The Champions League is where we want to be and the level we are aiming for. Now that we have arrived, it is time to enjoy ourselves, make the most of it and show everyone what we can do.
''Last season was key for us. We won our first trophy for 35 years and qualified for the Champions League, claiming a place amongst the best teams in Europe.''
He later added: ''We need to improve upon what we have achieved already and keep progressing as a team. We must finish in the top four in the Premier League and secure Champions League football every season.
''It's not enough just to do it once. Of course, we've got to do well in the Champions League and we should aim to win it. Why not? I don't think that is out of the question.''
Silva has been the standout performer in the opening months of City's campaign, even with fierce competition from a number of team-mates in a star-studded squad. The 25-year-old Spanish World Cup-winner, signed in a £26 million deal from Valencia last year, admits it took time adjust to English football but now feels he - and the team - are well settled.
He said: ''It took me a while to settle in and get going because it had been a long summer with the World Cup. I wasn't in the best shape without a regular pre-season.
''Then there were trips to Mexico and Argentina that messed up the programme a little bit - making it hard to settle and find my rhythm. But, bit by bit, I found my rhythm and started to feel a whole lot better.
''One of the reasons we're working better is because this group has settled as well. We qualified for the Champions League and have added a couple of players here and there who will help us step up a level. Hopefully that is going to show on the pitch. You'll see an improvement throughout this season as well.
''The team are coming together really well, players have been developing an understanding. There is definite improvement.That brings confidence, which allows us to express ourselves more and more. As the new signings settle, that will help us improve even more.''
