Manchester City return to Champions League action on Wednesday in a highly anticipated clash between the club that made Pep Guardiola's reputation and the one that hopes he can produce similar success for them.
Prediction: Barcelona has a strong home record in the Champions League and were undefeated in the last 17 matches at Camp Nou since 2013.
"I know all about him and of course so does [coach Pep] Guardiola - but then when it comes to Barcelona everybody in the world knows about all their players, so it doesn't mean so much", Aguero said. "They have important players, but we have to go there with the intention to do things well".
"City are the best team in my managerial career I have played against", Koeman added. They're a machine. For the last decade, the last 50 years, Barcelona dominate football matches. They have three unbelievable players in front, they use an a wonderful counter-attack, they have a good build up.They are a good team so when they win 4-0, they deserve to win 4-0.
The former Netherlands global said the two teams' possession-based styles would make for a fascinating encounter. "That's why in Spain the last six, seven, eight, nine years win, or reach the finals, semi-finals of all the European competitions, it's because they play good they are good player - that is the reason why".
"So I will never say to a player who wants to take the penalties 'no, I want someone else to take them'".
"I am here to try to make that happen", he said.
De Bruyne replaced Aguero as penalty-taker and his kick was a nice height for Stekelenburg, who parried the ball away diving to his left.
After a fruitless slog against a tightly organised Everton team at the weekend, City will be eager to meet a side that offers them space to breathe.
"Maybe we didn't deserve a point on chances but football is unpredictable and our goalkeeper maybe played his best game ever".
"You need to be a little bit lucky and a goalkeeper to have the match of his life, and you need a work-rate from your team". Hopefully now they will have all moved on from the doom and gloom feel that hung over the club for a week or two after the Bournemouth and Norwich games. "I spoke with my technical staff before the game, and I said that knowing Pep, we need to expect three defenders".
