Villarreal have surprised a few people in La Liga this season and their rise up the table has been aided by the form of Musacchio, who has played every minute of their 16 La Liga games this season.

The 23-year-old has started to come of age this year, helping his side to keep five clean sheets so far.

Chelsea boss Jose Mourinho has indicated he might have to start shutting up shop as he can't rely on his forwards to win them games. One way to do that is to bolster his defensive options.

A prime example of the problem facing the Blues boss came on Tuesday night.

Samuel Eto'o and Demba Ba missed good chances to kill off Sunderland in the Capital One Cup quarter final and Mourinho's side went on to pay the price by going out in extra-time.

Mourinho is known to be in the market for another defender, with his interest in former-club Inter Milan's Andrea Ranocchia widely known.

City are always on the lookout for talent as they strive to become a European powerhouse.
