Porto's midfield dynamo Hector Herrera is attracting major Serie A interest.

The Mexico international's profile has exploded since his starring performance in their shock World Cup win over Germany.

TMW says AC Milan are tracking Herrera in Russia and preparing a bid for the midfielder.

Herrera is also on the radar of Napoli, Juventus and Inter Milan, though it is the Rossonero which are showing the most concrete interest.

The 28 year-old has been with Porto since 2013, joining them from Pachuca.
