Barcelona are pursuing Eric Garcia from Manchester City.
The 19-year-old defender is a former Barca player, and the Catalan giants would like to bring him back.
ESPN is reporting that City denied Barca the chance to approach Garcia.
The Premier League giants want to ensure the centre-back is part of their future.
City manager Pep Guardiola sees him as a player he could use in the coming seasons.
One issue for City is the uncertainty around Guardiola's own future, which could tempt Garcia to seek pastures new if Pep leaves.
