Spanish media had claimed that Barcelona had identified Heung-min Son as a 'market opportunity' due to his expiring deal. Barcelona has been forced to make an increasing number of free transfer acquisitions in recent years due to financial problems, and Son was viewed as a viable target.

There were speculations linking Heung-Min Son with a move to FC Barcelona, but these rumors have been dismissed as he extended his contract with Tottenham Hotspur.

Heung-Min Son's contract with Tottenham Hotspur is expected to run out at the conclusion of the season, which would enable him to exit the club without a transfer fee. FC Barcelona is said to be keen on acquiring Son, given their financial limitations and his prospective availability as a free agent. The Daily Mail reported that Barcelona has expressed interest in Son and might initiate talks for a free transfer post-season. Tottenham has yet to start negotiations for a contract renewal with Son, leaving it uncertain if they will try to keep him.

Heung-min Son is rumored to have expressed a desire to join Barcelona, with the potential for a free transfer at the end of the season if he does not agree to a one-year extension with Tottenham. His current contract is set to expire in the summer. It is reported that Son's representatives are dissatisfied with Tottenham's choice to simply activate the one-year extension option in his existing contract rather than proposing a new contract. Given their financial struggles, Barcelona would be keen on acquiring a high-quality player like Son without a transfer fee.
