The Daily Mail says Bundesliga giants RB Leipzig, Dortmund, Bayern Munich have all expressed an interest in the 16 year-old attacking midfielder, but Barca are confident of clinching an agreement.
"A lot of young players are now training regularly with the first team," Norwich manager Philippe Clement said last month.
"Ajay is a very interesting one on that list, and I know also that he played in the training camp in the summer with the first team, and he did good stuff there. He's very young. He's still very young.
"But, of course, we want to keep our best talents, because that's one of the important things for the future and the things we discussed with the owners that they want also players out of our academy to grow and to go in the first team."
