Sven-Goran Eriksson's Manchester City revolution gathered pace as he made Brazilian international Elano his third signing in a matter of hours on Thursday.

Elano arrived from Shakhtar Donetsk for £8 million on a busy day for Eriksson, who had already swooped for Real Sociedad's Javier Garrido and Dinamo Zagreb's Vedran Corluka.

The Brazilian, who played a key role in his country's Copa America Venezuela 2007 victory last month, agreed a four-year contract just hours after Eriksson paid £1.5 million for Spain U-21 defender Garrido, who signed a four-year contract. Eriksson also added Corluka for an undisclosed fee, believed to be around £7 million, with the Croatia defender signing a five-year contract.

The former England coach had already signed Rolando Bianchi, Martin Petrov, Gelson Fernandes and Geovanni since arriving at Eastlands last month, and he isn't finished spending yet. Fiorentina striker Valeri Bojinov is next on his shopping list and the Bulgarian is believed to be in England to complete a £6 million move from the Serie A club.

Eriksson's spree has been bankrolled by City's new Thai owner Thaksin Shinawatra and has made them one of the Premiership's biggest spenders during the close season. City chief executive Alistair Mackintosh said: "This morning has proved to be an immensely productive one, the outcome of which is the acquisition of three top quality players for Manchester City.

"This has been achieved as a result of some tremendous team work and I would like to praise everyone involved for their efforts. I would particularly like to thank Dr Thaksin, without whom today's signings would not have been possible."
