Chelsea are closing in on the signing of Benfica midfielder Ramires. The Premier League champions expect to tie up a deal for the 23-year-old before the end of the week.

Ramires, who is due to undergo a medical at Chelsea in the coming days, would be the second addition to Carlo Ancelotti's squad following the arrival of Yossi Benayoun from Liverpool.

The Italian targeted the Brazil international after losing attacking midfielders Joe Cole and Michael Ballack earlier in the summer.

Reports have claimed Chelsea would be willing to pay around £17m for Ramires, who represented A Seleção at the 2010 FIFA World Cup South Africa™.

The former Cruzeiro man is part-owned by a businessman and the Blues would have to strike a deal that complies with Premier League regulations, which outlaw third-party ownership of players.

Benfica president Luis Felipe Vieira said: "Ramires staying at Benfica does not depend solely on us. We have a partner and we must respect the contracts."
