World’s seven best midfield duos, including Real Madrid maestros and Juventus’ mighty engine room

1) Nemanja Matic and Cesc Fabregas (Chelsea)

The ultimate good-cop/bad-cop duo, and the most balanced pair on the list. Cesc’s finesse and passing are perfectly counter-balanced by Matic’s leggy ruthlessness. The two are the key to Chelsea’s fortunes this season, and the Blues’ best signings in years.
