Barcelona are reportedly one of several clubs "tracking" Atletico Madrid star Koke.
According to Spanish outlet Mundo Deportivo (h/t Claudio Colla of TransferMarketWeb), Barca are monitoring the playmaker along with Chelsea and Manchester City, and he could cost up to €55 million.
The Spaniard has been a real star for Atleti since coming up through the academy and has firmly established himself as a key performer in midfield, where he brings guile and unbridled creativity.
Koke is enjoying another strong season with Los Rojiblancos and has produced three goals and eight assists for them in La Liga thus far, guiding his side to second in the table ahead of rivals Real Madrid.
