Whilst manager Ernesto Valverde could have opted to make changes against the newly-promoted minnows, he instead went with his strongest side on on Sunday.
That decision meant that the club's summer signings were once again left waiting for an opportunity from the bench, all €150m of them.
All four players have now made their official debuts for the club and are now looking to break into the side.
Vidal is the only player to have featured in all three league games to date, whilst Lenglet is yet to take to the pitch in the league, though he did start the Spanish Super Cup win over Sevilla.
Arthur was blooded in the second half against Alaves, whilst Malcom did likewise against Real Valldolid.
