The Brazilian midfielder is the team's ideal addition for the upcoming campaign.
The inability to live up to expectations in Oriol Romeu's recent performances and the obvious impact of Frenkie de Jong's injury absence have made it very evident to those in charge of Barcelona's transfer business that the acquisition of a holding midfielder is the team's top priority for the upcoming campaign.
Bruno Guimarães of Newcastle, who recently inked a new contract with the Magpies and has established himself as one of the best players in the position on the continent, is the club's ultimate target. If Barça can afford to pursue the Brazilian—which is doubtful given their current financial circumstances—that won't stop them from doing so.
However, the team might get inventive, and Mundo Deportivo suggests a trade for Raphinha, who the Premier League team has long wanted. If Guimarães expresses a desire to move to Camp Nou, Raphinha still enjoys a strong reputation in England, and Barça could command a high enough fee to make a swap financially feasible and attractive for Newcastle.
Given Bruno's significance to Newcastle and Sandro Tonali's absence from midfield due to his gambling suspension, this is a difficult deal to pull off, which makes Guimarães even more important to Eddie Howe's plans. Raphinha, on the other hand, has turned down numerous opportunities to leave Barça, and there's no sign that he's changed his mind just yet. Only a clear and express request from Bruno could start this conversation.
Though this specific deal seems unlikely at the moment, stranger things have happened in football. A lot could happen before the season ends that changes the landscape.
