The first name that comes to mind is Luis Suarez. The Uruguayan seemed to be out of action due to his serious injury, but the COVID-19 stoppage has allowed him to return in time for the home stretch.
His goals have been vital to Barça in recent years and his brilliant partnership with Leo Messi is duly noted when one is out of shape.
It is precisely the Argentinian who, of course, will be the centre of attention in the match. The best player in the world was reportedly injured just days before, but Setién confirmed that he is totally prepared to face Mallorca.
Griezmann completes the expected trident for the attack. The Frenchman had some good performances before the break, but he did not seem to have completely integrated the team as off yet.
Then there's Braithwaite and Ansu Fati. Both are raffled the position of fourth forward. And the match against Mallorca can give clues about the role that will have both after the reappearance of Suarez. The academy product has lost his momentum and has even been considered for a return to the youth ranks.
Besides, Arthur is also in the spotlight. The coach's words, which cast some doubt on his situation, the criticism received and the rumours about Pjanic's arrival make him another name to watch.
Finally, Semedo will also be in the spotlight, as his attendance to an illegal party might have caused some tensions. Setién has already made it clear that he will not take this fact into account in his decision, but it remains to be seen to what extent it goes unnoticed.
