A breakthrough was reached on a conference call between Inter and Manchester United after days of negotiations.
Inter initially demanded a fee of €60 million, but Manchester United were unwilling to pay that much.
And, according to Sportitalia, the Serie A heavyweights have agreed to reduce their asking price for Onana.
Inter believes that keeping the Cameroonian at the San Siro is no longer feasible.
The goalkeeper has already signed to terms with Manchester United and is excited about the transfer.
Inter also modified their stance, seeing that even at €55 million, they stand to benefit handsomely from the sale of a player they signed on a free transfer last summer.
The proceeds from Onana’s sale will enable Inter to sign the players they desire, most notably Chelsea’s Romelu Lukaku.
