Cape Town - Manchester City goalkeeper Willy Caballero believes it is vital that his side improve their defensive performance against Monaco on Wednesday.
Pep Guardiola's charges take a 5-3 lead into the second leg of their last-16 tie with the Ligue 1 leaders and Caballero wants a professional performance if they are to advance in the competition.
"We have to attack in the same way that we did here at the Etihad and if we do we'll create chances and score goals," he told the club's official website.
"But the most important thing is to defend better than we did in the first leg.
"We have to play in a very professional way, trying to control the game and showing our experience."
"Keeping our style will be very important if we want to be in the next round," he added.
"We are always focused on our attack and scoring goals. This is Pep's main idea. His way of understanding football is very clear and we try to develop this idea on the pitch."
City have kept three consecutive clean sheets in their last three games in all competitions.
Kick off is at 21:45.
