The club from Nottingham has watched their defender depart on a temporary basis, and although he never featured for Forest, his standout displays could lead to a permanent departure.
Cuiabano has thrived at Vasco da Gama.
Nottingham Forest full-back Cuiabano is generating attention from prominent European teams as reports suggest the player has little interest in coming back to the City Ground.
The Forest left-back is currently spending the season on loan at Brazilian club Vasco da Gama and has delivered strong performances, providing five goal contributions across his previous four matches.
He has established himself as an important figure for manager Renato Gaúcho, which has only intensified discussions regarding his long-term prospects.
Cuiabano has failed to make a first-team appearance for Forest after previously being loaned to Botafogo prior to his switch to Vasco in January.
According to Brazilian publication Globo Expertise, talent spotters from German clubs have been assessing players in the Brazilian championship and have identified Cuiabano as the standout defender under 23 years old.
It has been reported that two German clubs—Borussia Dortmund and Bayer Leverkusen—have made approaches, with both reaching out to Nottingham Forest and Vasco da Gama to discuss the possibility of securing the player.
The player himself is apparently not enthusiastic about heading back to Forest, citing challenges with adjusting to life in England.
It is understood he would consider moving to another European club, though Vasco da Gama could block any such transfer as the Brazilian club holds an £8.6 million purchase option.
Vasco are weighing up triggering that option despite the fact such a fee would be substantial for any Brazilian club.
Should Vasco take up the option, they intend to offer Cuiabano a contract running until December 2030.
