Lucas Torreira is heading to Arsenal for €30m spread out over three years, while Sampdoria teammate Ricky Alvarez goes to Guadalajara.
As reported yesterday, Torreira to Arsenal is practically a done deal, with Sky Sport Italia pundit Gianluca Di Marzio confirming the same figures.
Although the Uruguay international has a €25m release clause in his contract, the Gunners negotiated a deal for €30m that will be spread out in €10m instalments over the next three years.
He had also been in advanced negotiations with Napoli, who baulked at his wage demands.
Samp teammate Alvarez is also on his way out of the club, with reports of a €0.5m transfer to Mexican club Atlas Guadalajara.
