Pep Guardiola believes that "Manchester City" will face a particularly difficult task when they need to find a replacement for Sergio Aguero.
Celebrating his 32nd birthday next summer, the Argentine with "Man City" still has a contract valid until 2021.
"Replacing Sergio with another player will be one of the most difficult tasks," said P. Guardiola. "He is simply irreplaceable. We have another wonderful striker - Gabriel Jesus, but after Sergio's departure, another sniper will have to come to the team."
"The most important moment in the history of this club will not be when we maybe win the Champions League, but Sergio's goal to QPR, which helped the club triumph in the Premier League.
That moment is better than fighting for four titles last season. The best part is that Sergio contributed to all of these victories.
He will decide when he has to leave, but sooner or later it will happen. I have no doubt that the club will be ready to find a replacement for him, but it will certainly not be an easy task," added the Catalan.
Since 2011, the Argentine playing for "Man City" has already played over 350 matches and scored almost 250 goals.
