After making his Barcelona debut in Sunday's win over Valencia, Sergio Aguero spoke in a press conference on Tuesday ahead of the Champions League game against Dynamo Kiev.
Asked why he chose the No.19 shirt at Barça and not the No.10, he revealed: "When I signed, I decided I wanted the No.19, which I had worn with Argentina's youth teams. At that moment, the No.10 was Leo Messi's."
At the same time, he was asked about Ansu Fati: "He's doing very well. He has a special talent that we have to take advantage of. He's young. We have to help him keep growing.
"These days it's very difficult to stay at the highest level. The veterans have to support him. Everyone knows he's one of those talents that doesn't come through very often. The No.10 shirt fits him well."
On his own welcome from the fans at the weekend, he added: "I didn't expect it. I am really grateful. Now I have to return that affection."
