Under FIFA rules, players can only play for two clubs in a season, making Sunderland a potential destination if Guiu leaves Chelsea.
Le Bris mentioned that Guiu's experience playing for Sunderland earlier in the season could be a factor in his decision-making process.
He stated that Guiu is a "really good footballer" who is "really committed" and has a strong work ethic.
Le Bris also praised Guiu's personality, describing him as "coachable" and willing to learn and develop his skills.
However, Le Bris noted that Guiu's fitness level was not where it needed to be when he was at Sunderland, and the club's current squad is well-stocked with strikers.
