Per The Sun, Sporting are ready to demand in excess of Trincao's £50m ($65m) release clause because 50% of the winger's next transfer fee is owed to Barcelona. Sporting are said to be determined to recoup £35m ($45m) for the ex-Wolves star, but that would mean United paying a £70m ($90m) fee, as Ruben Amorim seeks to rejig his attack.
