The 22-year-old has received a contractual proposal and is receptive to the switch, according to Fabrizio Romano, with Marco Rose's side having already strengthened their defence this summer through the arrival of centre-back Antonio Silva from Benfica in a deal reported by British media to be worth around £26m.
Bournemouth's pursuit of young talent continues to define their transfer approach as they prepare for European football for the first time in the club's 127-year history, having finished sixth in the Premier League last season to qualify for the Europa League.
Any sale would represent pure profit for Sevilla given Juanlu came through the club's own academy, with Sevilla also set to retain a percentage of any future transfer. Bournemouth have offered him a four-year contract through to 2030, on wages well above what he currently earns at the Sanchez-Pizjuan.
An Olympic gold medallist with Spain at Paris 2024, where he scored the goal that sent his country to the final, Juanlu came close to joining Napoli last summer only for the Italian club to fall short of Sevilla's valuation, and has also previously been linked with Wolverhampton Wanderers and Nottingham Forest.
Despite maintaining a strong reputation in Italy, England now looks the most likely destination for a player regarded as one of the most promising academy products to come through at Sevilla in recent years.
Capable of playing as either a right-back or further forward on the right of midfield, Juanlu made his first-team breakthrough two seasons ago and has since become a regular fixture for Sevilla, extending his contract to 2029 last year after emerging as one of the club's most sellable assets.
His versatility and pedigree at international level have made him a consistent name in transfer speculation, and this represents the most advanced any move for him has been since interest first developed twelve months ago.
