Barcelona are reportedly concerned about Gerard Deulofeu's lack of playing time with Sevilla.
The Spanish attacker, who spent last season on loan at Everton, moved to the Estadio Ramon on a season-long loan towards the end of this summer's transfer window.
Deulofeu was expected to battle for a first-team spot at the Camp Nou this season, but was instead sent on loan with the view to gaining regular football.
That has not occurred at Sevilla, however, with the winger playing just 17 La Liga minutes this season, and according to Fichajes.net, Barcelona have made their displeasure known.
It is understood that Deulofeu already has a strained relationship with Sevilla boss Unai Emery.
