The 20-year-old is already one of the most sought-after players in Europe and he has been linked with a number of high-profile clubs.
Il Corriere dello Sport claims Juventus are also showing interest in the highly-rated midfielder.
Juventus scout Francesco Marino was in Brussels last night to watch the player in action in the Champions League clash against Anderlecht, which proves the Bianconeri are stepping up their interest in the player.
Isco has scored 6 goals in 38 La Liga appearances for Malaga since making a €6 million switch from Valencia.
The club official also made a check on Anderlecht striker Diumerci Mbokani, another player who has attracted the attention of the Italian giants.
The Congolese striker has netted 20 times in just 33 league games for the Belgian giants.
