The 22-year-old right-back is reportedly back on Barcelona's radar after previously attracting interest from the Catalan club during his time at Real Valladolid.
According to O Jogo, Fresneda remains a player admired by Barcelona sporting director Deco, with the club continuing to assess ways of adding depth and versatility to the defensive area.
Barcelona's summer transfer activity left what was described as a clear gap in the squad after the club were unable to bring in another defender.
The situation means defensive reinforcements could again become a consideration as the season develops.
Fresneda fits that profile, having previously been identified by Barcelona when he was emerging at Valladolid.
His return to the club's radar comes as his reputation continues to grow in Portugal.
The right-back is currently with the Portuguese club and is reportedly attracting interest from Barcelona because of his potential and ability to operate as a modern full-back.
The Catalan club are also mindful of the versatility already available within their defensive group, but another option could provide additional cover as the season progresses.
Fresneda's development has helped increase his value, with the defender having featured eight times so far this season.
That involvement has strengthened his position at club level and comes as his current side considers extending his contract.
Barcelona's reported interest therefore comes at a time when the Portuguese club would prefer to secure Fresneda's future.
The defender was already known to Barcelona from his time in Spain, meaning any renewed interest would not represent a completely new name on the club's recruitment list.
Deco's reported admiration is another factor behind the possibility of a return to the Barcelona radar.
The sporting director has continued to assess options capable of strengthening the squad, and Fresneda's age and experience make him a potential candidate for consideration.
Barcelona's defensive needs could ultimately depend on how the current season develops.
The club have several players capable of operating in different defensive positions, but the absence of another specialist addition during the summer has left the position as an area to monitor.
Fresneda consequently remains a player to watch as Barcelona assess their options.
For now, the reported interest comes alongside efforts from his current club to secure a new agreement, while his continued appearances could further increase his profile.
The 22-year-old already has previous experience of being on Barcelona's radar and is now reportedly attracting renewed attention from the Catalan side as they look again at defensive reinforcements.
