Barcelona are reportedly fearful of losing 16-year-old centre-back Eric Garcia to Manchester City.
Garcia is understood to have informed Barcelona that he will not be signing a professional contract with the Spanish giants, which has alerted a number of European clubs.
According to Goal, Man City lead the list of interested teams, with head coach Pep Guardiola confident of winning the race for a player that is regarded as one of the most talented youngsters in the La Masia academy.
Man City, who are said to have offered Garcia a three-year contract, are currently unable to sign academy players from other English clubs due to a transfer ban, but are free to discuss terms with youngsters abroad.
Gerard Pique, Cesc Fabregas and Hector Bellerin are among those to have left Barcelona at a young age to move to the Premier League.
