Chelsea have joined the race to sign Real Madrid sensation Isco, according to Metro.
The Blues endured a tough start to the season as they could only manage a draw against Swansea City and lost 3-0 away from home against Manchester City.
They added left-back Baba Rahman to their squad but it is clear that new signings are required in the midfield area as well.
The 23-year-old is believed to be also on Arsene Wenger's radar.
