#4. Arthur Melo
It took few years but it seems Barcelona have now found the perfect replacement for their departed legend, Xavi Hernandez, with their capture of Brazilian midfield maestro, Arthur Melo this summer.
After agreeing on a deal with Gremio over the purchase of the youngster last season, the Catalans have finally executed his transfer this summer.
The 22-year-old is a typical Barcelona midfielder, with his incredible style of play earning him a lot of comparison with two of the greatest midfielders to grace the Nou Camp - Xavi Hernandez and Andres Iniesta.
A specialist in holding possession and distributing decent passes, Arthur will help in orchestrating play from the middle of the pitch and allow Lionel Messi to focus on his attacking duties.
He will also help in creating chances for the attackers to score, of which the Argentine will also benefit.
