Manchester United have been handed a transfer boost after Nicolas Otamendi's agent revealed he wants out of Valencia.
Yaya Toure's agent has performed a U-turn and insists his client will remain at Manchester City this summer.
The 25-year-old centre-back from Madrid is a free agent having recently terminated his contract with relegated Osasuna.
A statement published on Sevilla's official website said Arribas would travel to the Andalusian club's pre-season training camp in Neuruppin, Germany, after passing a medical and putting pen to paper.
Sevilla were rebuffed in a bid to sign Arribas, who made 70 league appearances in two seasons with Osasuna, last summer.
