Uefa has ended its legal fight against Barcelona, Juventus and Real Madrid over their involvement in the proposed European Super League.
The clubs were among the 12 “founding” members of the breakaway league, which later collapsed.
The trio, who have refused to renounce the project, were being investigated for “a potential violation” of Uefa’s legal framework.
Uefa says it is now “as if the proceedings had never been opened”.
The moves comes after a court in Madrid ruled that Uefa should not punish the three remaining clubs.
