Despite completing the signing of Oscar earlier this week, Chelsea remain keen to make further reinforcements to their squad this summer. The Brazilian arrived from Internacional for a fee of £25 million, taking the Blues' summer spending in excess of the £60 million mark.

There are still gaps that newly-instilled permanent coach Roberto Di Matteo believes he needs to fill in his squad, however. Top of that list would appear to be at right-back.

With a deal for Inter's Maicon seemingly dead in the water, Chelsea have reportedly turned their attentions to Marseille's Cesar Azpilicueta. The Spaniard has said that he is aware of and "flattered" by the interest of the Blues and the French outfit have admitted that a deal for the 22-year-old could not be ruled out.

"Everybody has to sell before buying," said sporting director Jose Anigo, according to ESPN. "In effect, it could either be Stephane M'Bia or Azpi. But, for now, nothing has changed."

Chelsea are also actively seeking a striker to help fill the void left by Didier Drogba's departure this summer. While various names have been mooted, high on the list of targets is Napoli's Edinson Cavani. The Uruguayan has proven himself to be one of the best strikers in the world over the past two seasons and scored against the Blues in last season's Champions League.

Although Napoli would be extremely reluctant sellers and are sure to demand a mammoth fee, reports are increasingly suggesting that Cavani is interested in a move.

The latest of which suggests that the mugging of Cavani's wife, coming shortly after the couple's home was burgled, has led the player to consider his future in the city.

"It is not a good moment, but they are trying to get over it," said the player's agent Claudio Anellucci, according to the Daily Mail.

"She has left Naples to join Cavani. It is difficult to get used to the idea that these sort of things can happen to you.

"It is true that incidents of this type can happen to anybody, but the truth is they happen too often."

One man that looks unlikely to be added to Chelsea's striking options is Stevan Jovetic. Reports have intimated that the Blues made a £20 million offer for the versatile Montenegrin, but Fiorentina are determined to keep their star man for at least another season.

"I spoke to Jovetic"Description: and told him he is off the market for numerous reasons," said owner Andrea Della Valle, according to Sky Sports. "I hope he understood that.

"He is so young and has such a long career ahead of him that it is important he stays in Florence for a while.

"Jovetic has to remain with us for at least another year and I hope many more. He is one of the few genuine European talents, so it's only right that he stays.

"Stevan seemed pretty relaxed. He has to understand that in life other opportunities will cross his path.

Chelsea are also looking to increase the dynamism on the right side of their attack and have strongly pursued Wigan's Victor Moses in recent weeks. Reports claim that the Blues have had three bids for the 21-year-old rejected, the last of which is believed to have been £6.5 million. The Daily Mail now claims that Moses will push for talks with Wigan manager Roberto Martinez as the club continue to seeks £10 million, despite the player having just a year remaining on his contract.
