Barcelona manager Quique Setien has claimed that his side will be hurt by new rules allowing five substitutions per game instead of three.
La Liga has been suspended since March due to the coronavirus pandemic, but is eyeing a return on June 11 with the derby between Sevilla and Real Betis.
With teams having been sidelined for months and looking at playing a congested schedule over the summer, the International Football Association Board (IFAB) allowed a rule change earlier this month increasing the number of substitutions teams can make through the end of the 2019-20 campaign.
