Chelsea are believed to be showing significant interest in Real Madrid's Isco.

Diario Gol is reporting that the Blues have joined Arsenal and Manchester City in the chase for the Spanish playmaker who has been in and out of Zinedine Zidane's starting XI this season.

It is understood that Isco, 24, is determined to win over Zidane and become a Madrid regular but there is definite interest from the Premier League which the player is pondering.

According to the report, Isco's father and agent, Paco Alarcón, has been contacted by Chelsea, the Gunners and City as the English trio circle ahead of the January transfer window.

Chelsea boss Antonio Conte is eyeing Isco as a possible replacement for Cesc Fabregas, Arsenal's Arsene Wenger sees him as a long-term candidate to step into the boots of Santi Cazorla and Pep Guardiola simply wants to further strengthen the City squad he inherited in the summer.
