Chelsea are currently working hard to add to their squad after facing challenges in the defensive area with no relying defense.

The Napoli defender kalidou Koulibaly has been on Chelsea radar since the January transfer window, and it looks like Chelsea will light back their interest in the Senegal star.

Reports states that Chelsea are planning to complete their deal this week as they were earlier linked with €90m star.

Since Chelsea has been denied to sign the Senegalese due to the age grade, another option from Sporting Lisbon has been emerged as the right alternative to replace Koulibaly.

Eduardo Quaresman has been followed by premier league clubs and Chelsea happens to fall among the contenders.

The defender has made his debut for the Sporting Lisbon this season, and has shown an excellent style of play. Chelsea will need to pay an amount worth €45m to bring the star to Stamford Bridge this summer.
