With new manager Antonio Conte joining Chelsea after Euro 2016, the Blues are primed for a big summer transfer window to improve on their very poor Premier League season.
However, the Stamford Bridge club were handed two serious transfer blows this week. Chelsea have told Everton they will not just give the Toffees what they want for Romelu Lukaku.
The Belgian striker has made it clear he wants to leave Goodison Park and is open to a return to Stamford Bridge. However, the Blues will not pay the £65 million Everton are demanding and will turn elsewhere if the Toffees refuse to negotiate a lower fee, according to The Daily Express.
Meanwhile, The Evening Standard released a report that Koke has no intention of leaving Atletico Madrid anytime soon. The 24-year-old Spanish playmaker has been a long-time target of Chelsea after making his senior debut for the La Liga giants in 2011.
However, Chelsea are not easily deterred and are chasing a duo of central defenders, which are two surprising names. According to Italian source TMW (via Bleacher Report), representatives of River Plate defender Emanuel Mammana are in London to hold talks with the Blues over a potential summer move.
The 19-year-old Argentine looked set for a move to Serie A club Fiorentina in January, before negotiations collapsed over the transfer fee. AC Milan and Napoli have also been linked with Mammana.
The Blues are also weighing up a move for Simon Kjaer, according to Turkish source Fanatik (via talkSPORT). Struggling to adhere to the rules of Financial Fair Play, Fenerbahce are likely to sell the Danish centre-back.
The 27-year-old Denmark international joined the Super Lig club this summer for £5.7 million from Lille after spells at Wolfsburg, AS Roma and Palermo.
