Barcelona Transfers: 10 Players They Must Sign This Summer

He may share a name with your granddad, but don't let that fool you. Arthur has emerged as one of the brightest young talents in Brazil over the past year, courting the attention of a host of clubs in Europe as a result.

In fact, he already agreed a move to the Nou Camp back in March, which means that this isn't so much a "could happen" as it a "definitely will happen" once he formally signs on the dotted line in July.

Still, this move is just too big to ignore. Barca are paying Gremio more than €30m for their 21-year-old playmaker, even though he's yet to turn out for his international side (albeit an international side with a frankly ridiculous level of depth).

According to scouting reports, Arthur is cut from the same cloth as midfield schemers like Cesc Fabegas and Thiago Alcantara, which would make him an ideal candidate to replace the outgoing Andres Iniesta. Talk about good timing.
