Barcelona have issued an ultimatum to Atlético Madrid, demanding a response to their offer for Argentina striker Julián Álvarez by July 31, according to ESPN FC's Transfer Talk.

The Spanish giants are pressing for a swift resolution as the summer transfer window progresses, signalling that their patience has limits. If Atlético Madrid fail to accept the proposal before the deadline passes, Barcelona could walk away from the deal entirely.

Álvarez has been one of the most coveted forwards in European football, with his performances for both club and country attracting significant interest from top clubs. Barcelona's decisive move suggests they are serious about landing the Argentine this summer.
