Real Madrid and Atletico Madrid are both reportedly keen to sign Chelsea wing-back Marcos Alonso before this summer's transfer window closes for business.
Alonso joined Chelsea from Fiorentina in 2016, and has scored 15 times and registered nine assists in his 84 appearances for the Blues in all competitions.
Atletico are said to be seeking a new left-back as Filipe Luis nears a move to Paris Saint-Germain, while Real are also in the hunt for a new signing before the end of the month.
According to Marca, both Atletico and Real are interested in signing the Spaniard, and each club is weighing up a £27m bid ahead of the closing of the transfer window.
Alonso scored the winner as Chelsea made it back-to-back victories at the start of the new Premier League campaign with a 3-2 home success over Arsenal at the weekend.
