18-year-old Moriba has been with the Catalan giants since he was seven years old, progressing through the club’s La Masia academy and now regarded as one of Barca’s brightest talents.
Ronald Koeman has set about introducing the midfielder to the first-team in recent months, handing him a senior debut in a Copa del Rey clash against Cornella in January with the player making his La Liga debut against Alaves in February, marking the occasion with an assist.
The Spain Under-18 international came off the bench as Barcelona sealed a memorable fight back against Sevilla to book their place in the Copa del Rey final on Wednesday.
According to Mundo Deportivo there are several clubs across Europe interesting in prising Moriba, who is represented by super-agent Jonathan Barnett, away from the Camp Nou.
With his current contract set to expire in the summer of 2022, United have already made an offer for his services, along with RB Leipzig.
The youngster is said to have a €100million release clause written into his current contract.
Barcelona fought back from 2-0 down in the first leg to seal a 3-2 win over Sevilla this week. They will meet Athletic Bilbao, last season’s winners, in the final in April.
