Barca also said Arthur’s buyout clause was to be set at a staggering 400 million euros, a move to prevent a potential repeat of the circumstances in which Paris St Germain signed Neymar from the Catalans by paying his 222 million-euro release clause in July 2017.

The 21-year-old is known for his passing ability. Another of his qualities is his ability to lose his man, a factor that makes him a danger close to the opponents’ area. “Arthur also stands for his skill at protecting the ball and his eagerness to play vertically up the field,” the club said while praising the Brazilian midfielder.

Arthur started his career in 2008 in the youth teams at the Goiás Esporte Clube before moving on to Porto Alegre club Gremio in 2010. He made his way to the first team under coach Luiz Felipe Scolari.

The midfielder later became a vital figure in the team that won the Copa Libertadores in 2017 in which he was named the man of the match in the second leg of the final against Argentine side Lanus.
