The agents of Sergio Aguero say the Atletico Madrid star hasn't been unsettled by European interest in the early months of this season.

Manchester United manager Sir Alex Ferguson watched Aguero in action last Sunday at Barcelona, while the striker is also a major target for Juventus.

IMG's Maxi Lo Russo said: "We are calm. We are only at the beginning of the season, we are in constant contact with Atletico Madrid. We'll see what happens, if there's news it will be made public."
