Barcelona have reportedly set their sights on Juventus star Matthijs de Ligt and Inter Milan centre-back Milan Skriniar as their new defensive options for the upcoming season.
The Catalan giants also have their eye on fellow Juventus players Daniele Rugani and Mattia de Sciglio, identifying a number of Serie A targets for the next campaign.
According to Mundo Deportivo, Barca would be willing to swap both Samuel Umtiti and Nelson Semedo in deals, with the coronavirus pandemic financially affecting the Spanish champions.
Barcelona have been long-term admirers of De Ligt, with the La Liga outfit showing interest in the 20-year-old before his move to the Old Lady.
With Quique Setien desperate to strengthen the defence of his squad, Skriniar is also a promising option for the manager.
Both defenders have also attracted interest from Premier League side Manchester United.
