Manchester City are reportedly set to sign Argentine marksman Sergio "Kun" Aguero in the blockbuster move of the transfer window to date. The electrifying Aguero will join City for a reported $63 million dollar transfer fee from Atletico Madrid, making him the second most expensive Premier League signing of all time, second only to Chelsea's Fernando Torres.

The move is a massive boost to City's fortunes, potentially giving them four of the world's top strikers to deploy and a signal that they are no longer merely "noisy neighbours" to giants and arch rivals Manchester United. Aguero, who is reportedly set to earn a staggering $12.5 million per season in wages on a five-year deal, can form a potentially lethal forward line up alongside fellow Argentine Carlos Tevez, Italian Mario Balotelli, and Bosnian Edin Dzeko.

But, with Tevez agitating for a move away from Eastlands, City now have a partial replacement for the club's MVP in the high-powered Aguero. Aguero led Atletico with 27 goals last season across all competitions with twenty in league play; and while Argentina disappointed at this year's Copa America, Aguero netted three goals, including a critical late equalizer in their first group game against Bolivia.

Moreover, the move is a massive psychological boost to a club that has seemed oddly aimless in the off-season. City had so far been quiet in the transfer market this summer, picking up only Arsenal back Gael Clichy for a reported $11.5 million and Montenegrin back Stefan Savic for $16 million. This pales in comparison to United, who had hoovered up David de Gea, Phil Jones and Ashley Young in a binge valued at $80 million.

No more. With the capture of Aguero, City have not only fired a shot across United's bow, they have gained the extra carrot to dangle in front of their other major target: Arsenal's creative midfielder, Samir Nasri.

On paper, the signing is a smart one, given that it was made before the bite of UEFA's Financial Fair Play regulations can kick into full effect. City have cleared some room by dispatching Jerome Boateng to Bayern Munich and Shay Given to Aston Villa, but their latest overall losses were in excess of $200 million, and they currently have several high-priced talents -- including Craig Bellamy and Emmanuel Adebayor -- sitting fallow on staggering weekly wages. City have only until the 2013-14 season to get their books in order with UEFA and have already come under intense criticism from rivals Liverpool and Arsenal for a perceived "gaming" of the system that includes a novel naming rights deal with Etihad Airlines for Eastlands valued at a staggering $660 million over 10 years.

For Atletico, it is an admission of defeat. They gave up `keeper de Gea to City's crosstown rivals Manchester United in a $37 million move after finishing a miserable seventh last season. And the exodus is not over. Diego Forlan is reportedly heading for the door as well, while Atletico's summer pickups have been decidedly tepid.
