Atletico Madrid are concerned that the decision by Spain's National Sports Council (CSD) to allow Barcelona to provisionally register Dani Olmo and Pau Victor sets a dangerous precedent, the LaLiga club said on Thursday.

Atletico Madrid have issued a statement to express the club’s “deep concern” at the decision by the CSD to allow Barcelona to register Dani Olmo and Pau Victor on a temporary basis. The two players are now available to play for the Catalan giants once again after Barca took their appeals to the Spanish government.

Spain's government has stepped to provisionally allow midfielder Dani Olmo and forward Pau Víctor to continue playing for Barcelona following the Spanish league's refusal to do so. Barcelona appealed the decision by the league to Spain's Higher Council for Sport.

FC Barcelona has reportedly entered the bidding for a Manchester United star, who could join it in the ongoing winter transfer window.

Barcelona's squad issues extend beyond just the eligibility of Dani Olmo and Pau Victor, and a new report suggests another player has been green-lit for an 'immediate sale' to help ease their situation.

Arsenal have now joined the race for Ronald Araujo, the talented Barcelona defender who is expected to leave the Catalan club during this transfer window.
