Right now, Barcelona is only two wins away from winning the La Liga title. Although football is often unpredictable, it is foreseeable that the team will end up winning the title several days in advance, which would leave many matches unplayed for a title they have already won, and would just replicate the goaless and aimless draw against Huesca.
To avoid this, there are several things Barcelona has to do. The most important is, of course, to stay focused and continue preparing both the Champions League and the Copa del Rey. Although Valverde could start some less common names in those matches, it should not entirely distract the rest of his team for what's to come. Moreover, this is particularly relevant now, as the team is in great shape and have reached a high level of performance that they will want to keep if they want to win a coveted treble.
In addition, Barça could help Messi win a new Golden Boot. The Argentine, who did not score against Real Sociedad and did not play against Huesca, now has a worthy rival for the prize: Kylian Mbappé, who is just three goals away.
With five rounds to go, it seems the fight for the award is more open than ever, with Mbappé's slight advantage from the recovery of PSG headlines and the greater weakness of Ligue 1 rivals, who in many cases are dominated by the Parisian team.
If the Golden Boot is a minor trophy compared to a hypothetical treble, the second places of Luis Suarez and Ter Stegen in the 'Pichichi' and 'Zamora' do not seem attractive enough to get the team's attention.
In the case of the German goalkeeper, with the Cup final just around the corner, it is not impossible that Valverde ends up starting Barcelona's second goalkeeper Cillessen in some of those clashes, but this of course depends on how far Barcelona manages to get in the Champions League.
