According to Superdeporte, Valencia will miss out on performance-based payments that formed part of the deal that took André Gomes to Camp Nou in the summer of 2016.
Barcelona paid a fixed fee of €35 million for the Portugal international, plus up to €20m in add-ons. One of those add-ons is based on Barcelona's performance in the Champions League during the five years of Gomes' contract. Valencia receive €500,000 if Barcelona reach the quarter-finals, plus €1m if they reach the semi-finals, an additional €1m if they reach the semi-finals, and a further €3m if they win the tournament. That equates to €5.5m if Barça lift the Champions League in any given season.
Barcelona have exited the competition at the quarter-final stage in both of Gomes' seasons at the club (incidentally, both defeats were to Serie A teams: Juventus last season and Roma this one). That means Valencia have only pocketed €1m of a possible €11m from the Champions League clause.
