Barcelona will receive a €1m bonus from Inter as part of the agreement for the transfer of Arturo Vidal and the Chile international will get an automatic pay rise.
The Chile international joined the Nerazzurri as a free agent last summer.
The agreement came with a set of bonuses based on the player’s performances and the club’s results.
According to Calciomercato.com, the Serie A side will pay Barcelona a €1m bonus after winning the 19th title in their history, the first one in over a decade.
José Mourinho had been the last coach to win the title in the 2009-10 campaign.
Vidal signed a €5m-a-year deal with Inter, but according to a previous La Gazzetta dello Sport report, his salary will increase to €6.5m-a-year in 2021-22.
According to reports in Italy, the former Juventus and Bayern Munich star is one of the players who could leave the Stadio Giuseppe Meazza at the end of the season as Steven Zhang has warned the club to cut costs.
