Barcelona boss Ernesto Valverde insisted he is unconcerned over Levante's official complaint regarding their selection of Chumi in the first leg of their Copa del Rey clash.
Young defender Chumi started last week's 2-1 loss to Levante despite being due to serve a suspension after picking up five bookings while playing for Barcelona B in the Segunda Division B.
Barca won the reverse fixture at Camp Nou 3-0 on Thursday - Ousmane Dembele scoring twice and Lionel Messi adding the third - to advance to the quarter-finals courtesy of a 4-2 aggregate success, with the draw for the last eight due to take place on Friday.
