The 19-year-old has fallen further down the pecking order at Chelsea following the arrivals of Liam Delap and Joao Pedro.
According to Sport, RB Leipzig, who are preparing for life without Benjamin Sesko are interested in bringing Guiu to the Bundesliga.
A potential deal for the Spaniard won’t be straight forward, however, Fabrizio Romano has reported that Premier League new boys Sunderland are also interested.
Guiu played just 71 one minutes in the Premier League last season but managed to score six goals in Chelsea’s Europa Conference League winning campaign before picking up an injury early in 2025.
