Barcelona have allowed La Liga rivals Atlético Madrid to sign Tottenham Hotspur defender Cristian Romero after deciding against pursuing the Argentine themselves this summer.

Romero's name has been a staple of the Spanish media headlines throughout the summer window. After word emerged that the 28-year-old had decided to depart Tottenham, both Barcelona and Atlético were quickly linked with moves for his services. The departure of Ronald Araújo to Liverpool only intensified the links with Barcelona, as Romero was tipped to join Pau Cubarsí in a World Cup-winning defensive pairing at the Spotify Camp Nou.

However, as confirmed by multiple sources over the last 24 hours, Romero is instead Metropolitano-bound. Atlético agreed to fork out a sum in the region of €40 million to land Diego Simeone's fellow countryman.

Market insider Fabrizio Romano revealed that this development came after the Barcelona board, in conjunction with Hansi Flick, "decided against the move." The reasoning behind the decision has not been made public, but it leaves Barcelona with questions to answer in defence following Araújo's exit to Anfield.

For Atlético, Romero's arrival represents a significant statement of intent as they look to mount a serious challenge on multiple fronts under Simeone. The Argentine international brings Premier League experience and World Cup pedigree to a defence that will be expected to compete at the highest level.
