Alexander Barboza has requested a salary increase and has also requested non-financial guarantees from Botafogo. The player's staff seeks assurance regarding the permanence of the club's directors. In an interview with 'Canal Vasco' and 'VDG-CAST', Barboza's agent, Juan Cruz Oller, stated that Barboza will renew if director of sports management Alessandro Brito and trading director Deive Bandeira stay at Botafogo. From Botafogo's perspective, Barboza's permanence is considered essential, even with a possible salary increase. The club is in a delicate financial situation and has delayed image rights payments. In January, the player's staff and the club's management had agreed to renew the contract until the end of 2029, but it has not yet been signed. After winning the Taça Rio in early March, the defender stated that the negotiation was stalled. Barboza also explained to the Arena Alvinegra channel that everything is stalled, and that while the contract terms are agreed and the amount he is asking for to renew is not large, he needs security.

The staff of 30-year-old Argentine centre-back Alexander Barboza and the Botafogo board reached an agreement for a contract renewal until the end of 2029 in mid-January. The contract, however, has not been signed since then. Alexander Barboza stated that the situation has not progressed and that he has already indicated his requirements for renewal, which are not extensive. According to Barboza, the contract terms are agreed upon, but he needs security. The player wants guarantees regarding the future of the club's project. The period during which the club was under a transfer ban at the beginning of 2026 greatly influenced this process. Alexander Barboza is urging the management for more stability. Barboza, who joined Botafogo in January 2024, has a current market value of €5.00m, according to Transfermarkt. In the current domestic league season, he has made 3 appearances and provided 2 assists.
