Barcelona are ready to pounce if Manchester United fail to tie down Adnan Januzaj to a new contract, reports the Daily Mail.
Januzaj sent shockwaves through European football after his awe-inspiring Premier League debut for the reigning champions.
The player scored two goals, giving Manchester United a 2-1 win over Sunderland, which was vital to take some pressure off new manager David Moyes.
But after just one game in the Premier League, Januzaj's future at Old Trafford is already in doubt as he is yet to pen an extension to his current deal, which expires next summer.
Barcelona are well aware of the talents of the young Belgian having tracked him since he first moved from Anderlecht to Manchester United in 2011.
The Daily Mail is reporting that officials at Barcelona have a growing confidence of luring the 18-year-old to the Nou Camp when his deal expires.
Januzaj has insisted that he is happy at Manchester United but there are fears within the club that his father will play a major part in where he ends up.
The players agent Dir de Vriese has also confirmed interest in the player is high, saying to reporters last week: "I’m not going to say which teams are interested in him, but I can tell you that there is interest from several European clubs."
If Januzaj was to leave for Gerardo Martino's team it would represent a third significant blow for United's youth academy in just two years.
Paul Pogba and Ravel Morrison were widely thought to be the jewels of their generation at Old Trafford but differing reasons saw the pair exit prematurely in 2012 for Juventus and West Ham respectively.
Pogba has since gone on to nail down a first team place for the Serie A champions whilst Morrison impressed for West Ham with a wonderful solo goal against Tottenham on Sunday.
