4. Dani Carvajal
Although Ivanovic is a Chelsea legend who has served at the club for many years it is time that the Londoner get a new first choice right back. The Serbian has been really bad this season and has often left Chelsea too exposed down the right. Carvajal could be the perfect problem to Chelsea's woes at defence.
The Spaniard has been second choice to new Real Madrid signing Danilo for most of the season and he seems to be unhappy at the Bernabeu. Manchester City and Manchester United are also reportedly in pursuit of his signature but Chelsea can come out on top.
The 24-year-old Spanish international came through the Real Madrid academy and broke into the first team in 2013. He has earned the praise of many experts with his great displays for Real Madrid. He's a good young talent and he can be a great signing for Chelsea.
