According to Spanish publication 'Marca', the Catalan giants are already putting the finishing touches to a professional contract for the starlet ahead of his 16th birthday in January, with the likes of Manchester City already hot on his heels.
Barca are thought to be loathe to lose one of their brightest prospects and are thus attempting to convince him to stay by offering him generous terms after a seried of impressive performances within the club's youth set-up.
A hat-trick against Real Madrid back in August did nothing to temper the expectations of a player who was only born in 2003.
Moriba's physicality and imposing stature have already seen him compared to the likes of Yaya Toure and Paul Pogba, with Barca keen to ensure he does not become "the one that got away".
