RB Leipzig have made sure to protect themselves from losing Angelino.
The former Manchester City fullback was signed permanently on the weekend after triggering an appearances clause in his original deal.
Victory over FC Augsburg saw RBL complete the signing of Angelino for €18m.
And in his new contract, the Spaniard has seen a €60m buyout clause inserted.
Angelino had spent the past 12 months on-loan with RBL before Friday night's game.
