Manchester City have insisted on a buy-back option in Angelino's deal with RB Leipzig.
The Spanish left-back has returned to RBL on a season-long loan with the option to sign permanently.
The Manchester Evening News says the purchase option of €20 m will be converted into a purchase obligation, provided that the Spaniard plays 12 competitive games for Leipzig in the coming season. Five of these must be completed at least in the second part of the 2020/21 season.
City has also secured a buy-back option of €40m in the agreement.
