Joaquín Martínez Gauna, known as Oso, made a significant impact at Sevilla last season, with the player from Torrevieja making his mark in games including the local derby. His emergence has generated growing interest from clubs in Spain and beyond, though Sevilla are working to extend his contract.
Fiorentina's interest follows reports that the club had already enquired about Sevilla's right-back Juanlu Sánchez alongside Atalanta, making this a second approach to the Andalusian club as the Italian side look to strengthen their defensive options.
The Italian club's interest in multiple Sevilla players reflects the transfer market pressure the Andalusian side faces this summer, with the need to generate funds creating opportunities for clubs willing to move decisively. For Oso, any European interest at this stage of his career would represent a significant step forward for a young player who has only recently established himself in the first team.
Whether Sevilla would entertain an offer for a player they are actively looking to retain remains the central question, but Fiorentina's track record of moving early and convincingly in the market means their interest cannot be dismissed lightly.
The contract talks currently under way at Sevilla will be a key factor. If an extension can be agreed before Italian clubs formalise their approach, the situation becomes significantly easier for the Spanish club to manage.
Fabio Grosso's Fiorentina have been active across several positions this summer and the left-back slot appears to be among their priorities as they build towards next season's campaign.
