Barcelona reportedly view Ilaix Moriba as an 'essential' player for the club's future, with the Catalan giants working to convince the youngster to pen a new deal at Camp Nou.
The 18-year-old has made the breakthrough into the club's first team during the 2020-21 campaign, featuring on eight appearances in all competitions, providing three assists and one goal.
Moriba's contract is due to expire next June, though, and Manchester United continue to be strongly linked with the midfielder.
A recent report claimed that the 20-time English champions had made a 'firm offer' for the youngster as they attempted to bring him to the Premier League.
However, according to El Confidencial, Barca regard the academy product as one of their untouchables and will fight to convince him to commit his future to the club.
The report claims that Lionel Messi, Marc-Andre ter Stegen, Ansu Fati and Pedri are also among those viewed as vital to the team's plans moving forward.
Moriba scored his first goal for Barca in their 2-0 win over Osasuna at the start of March.
