ESPN reported that Flamengo's management has authorised Allan to seek a new club and that he will not remain at the club for 2026. The player was informed of his departure prior to the Intercontinental Cup in December.

Flamengo will evaluate Allan's situation if proposals arrive, because he is not a priority for the coaching staff. The player wants more playing time, and the red-black club will consider the financial aspect for a negotiation.

Allan is one of two players expected to leave Flamengo. He has been left out of the last squad lists for technical reasons and is not part of the club's current plans, which has led him to seek other alternatives.

The columnist for Jornal O Dia, Fabrício Lopes, stated that Jorge Sampaoli, the coach of Atlético-MG, is interested in the repatriation of 28-year-old Brazilian midfielder Allan from Flamengo (who has already played for the alvinegro team). The player's contract with Flamengo is set to expire on December 31, 2027, and his market value is currently estimated by Transfermarkt at €4.00m.
