#4. Xavi Hernandez
One of the finest central midfielders of all time, Spanish International Xavi Hernandez is also one of the few Barcelona superstars who were able to establish a fruitful connection with the Argentine maestro during their time together at the Nou Camp.
Also a product of La Masia, Messi and Xavi both emanated from the same Barcelona youth system, and although the midfielder became a Blaugrana before Messi, they both shared the brightest moments of their careers together.
Both superstars were pioneers of Barcelona's golden era under Pep Guardiola, enforcing the Blaugrana's famous tiki-taka system that brought a lot of fortune to the Nou Camp including a historic sextuple in 2009. They shared a telepathic relationship during their times together and they could find each other on the pitch even with their eyes closed.
