Long story short, this guy is not-so-quietly the best midfielder in La Liga, *bar none*.
You play him in defensive midfield, central midfield, in the hole, on the wings...he will be central to the game every time. He led Betis, and *La Liga*, in xG contributions (xG + xG assisted) for a while, and has amazing tackle figures, tackle success rates, possession regains and deep progression rates. 16 goals last season, and 6 assists.
Here he is against Madrid away -
He's a complete midfielder, equally comfortable at No.10 or in defensive midfield, and seems like probably the closest thing to an Eriksen replacement we're likely to find.
I am definitely hyped for this guy, although if it's at Eriksen's expense....
