Barcelona have been cleared of all charges regarding allegation the club made payments to referees’ chief.
In March the UEFA governing body was looking into claims that the Catalans made transactions to one of the referee main bodies.
The team dismissed all the claim and pleaded innocence.
The club still remains under threat as UEFA reserves the rights to punish them in the future, despite giving the green light on the Champions League.
It was alleged that Barcelona paid 8.4m euros (£7.4m) to Jose Maria Enriquez Negreira, the former vice-president of Spain’s referees’ committee and his Dasnil 95 company.
UEFA’s statement said:
“The investigators in charge of the case are invited to continue and finalise their investigation and to send a further report to the appeals body if and when they consider that the admission/exclusion of FC Barcelona [in the Champions League] should be assessed.”
