Sergio Ramos has reportedly fallen out with Real Madrid coach Carlo Ancelotti, increasing speculation that he wants to leave the Bernabeu.
The Italian coach was seen criticising the 27-year-old centre-back after he was sent off during Los Blancos' 4-1 victory over Galatasaray on Wednesday.
Chelsea and Manchester City have both been linked with the Spanish international, who was already believed to have been angered at not receiving a pay rise following the arrival of Gareth Bale.
According to The Mirror, Chelsea and Manchester City are both monitoring the situation in the Spanish capital.
Ramos, who has been sent off 17 times in his career, has fallen behind Pepe and Raphael Varane in competition for a spot at centre-back, with Ancelotti using him as a right-back.
