10 footballers who can sign a pre-contract in January

#8 Hector Herrera (Porto)

Hector Herrera is clear in his intention to leave FC Porto

The eighth player on this list is Porto's midfielder Hector Herrera. Herrera is clear in his intention to leave the club as he has already rejected three contract extension offers. The Mexican is well aware of the interest in him so obviously, he wants to leave Portugal and find himself another challenge.

Herrera is also Porto's captain and one of their best players on the pitch. His presence in the midfield line brings a lot of security for their defensive line. He is also a very experienced player who can improve even the best European teams. The reports say that Arsenal is the latest club which is monitoring the situation around Herrera as Unai Emery looks to rebuild his midfield line. Herrera is of 28 years age and this is probably the best time for a transfer to a big club.
