Chelsea have reportedly targetted Benfica's young Spanish midfielder Javi Garcia, during the summer transfer window. The Blues are believed to have sent scouts to watch the Portuguese club's league game against Maritimo on Sunday, with a view to opening talks. According to the Daily Mail, the London club were also observing striker Nelson Oliveira.

Garcia, a product of the Real Madrid youth academy in Spain, has recently signed a six year contract with his club but the Portuguese are reportedly willing to negotiate a deal if they receive an offer in the region of £25 million. Chelsea's league rivals Manchester United have also shown an interest in the 25 year old, in recent months.

Garcia operates primarily as an anchorman and put in an impressive performance in both legs, when Chelsea and Benfica met during the two sides' Champions League quarter-final ties. In fact, Garcia even scored, at Stamford Bridge. The player made 20 appearances for Madrid, during the 2008/09 season and has played for Spanish club Osasuna. He joined Benfica in 2009.

Meanwhile, it also believed that reigning Spanish and European champions Barcelona were at the same game; they were watching Olivieira.

The 20 year old Portuguese has made only 15 appearances, in all competitions, for Benfica this season but has clearly done enough to merit attention from Barcelona and Chelsea. The young Portuguese scored four goals in the Under-20 World Cup last year and made his debut for the national side earlier this season.

In other transfer news, it appears Turkish club Besiktas are ready to battle Tottenham for Chelsea forward Salomon Kalou.

The Ivorian, who has been a long term target of Spurs boss Harry Redknapp, will be a free agent at the end of the season and a Daily Mail report suggests the Turks' representative has held talks with the player's agents in London, about a potential move in the summer. Besiktas are understood to be ready to offer Kalou a lucrative contract, if the 26 year old decides to move to Turkey when the transfer window opens.

Chelsea, are sixth in the league, with 58 points from 38 games and welcome relegation battling Queens Park Rangers to Stamford Bridge on Sunday in the west London derby.
