The on-loan star is allowed to feature against his parent club.
The controversy surrounding whether Chelsea loanee Thibaut Courtois can play for Atletico Madrid against his parent club in the Champions League has been decided by UEFA.
After drawing each other in the semi-finals there was debate about whether the Blues would demand a fee to be paid by Atleti to allow Courtois to feature against the club that owns him.
Yet alongside precedent UEFA have decided that the Premier League side cannot demand that the goalkeeper does not play or that a fee has to be paid.
“In response to media reports referring to the situation of Club Atlético de Madrid goalkeeper Thibaut Courtois, UEFA would like to reiterate its position,” the statement read.
“The integrity of sporting competition is a fundamental principle for UEFA.
“Both the UEFA Champions League and the UEFA Disciplinary Regulations contain clear provisions which strictly forbid any club to exert, or attempt to exert, any influence whatsoever over the players that another club may (or may not) field in a match.
“It follows that any provision in a private contract between clubs which might function in such a way as to influence who a club fields in a match is null, void and unenforceable so far as UEFA is concerned.”
This is the second time this season that a loaned player has featured against his parent club, when Mo Bangura played for IF Elfsborg against Celtic.
It has sparked a debate as to whether the loan system needs to be evaluated, especially with clubs such as Chelsea currently having 26 players temporarily away from Stamford Bridge.
