Atletico Madrid have completed the club record €23 million (£15 million) signing of young Independiente playmaker Sergio Aguero.
The 17-year-old had been linked with a host of Europe’s top clubs including Bayern Munich and Liverpool, and the move signals Atletico’s intent to build a squad capable of challenging domestically and in Europe.
Along with Barcelona’s Lionel Messi he is considered the brightest prospect in Argentinian football.
“For Atletico Madrid it is the most important signing of a 17-year-old in our history,” said Atletico director general Miguel Angel Gil.
“I have no doubts that Aguero will become a major star in Europe.”
Aguero netted 23 goals in 54 appearances for Independiente and Atletico have handed him a six-year contract.
