I am sure Barca will beat Alaves with more than 3 goals. Trio MSN will show again, this is an easy match for barcelona, I hope after making 3 goals soon Messi and Suarez replace with other player to meet PSG in the CL match.
when viewed from the quality of the players of each team is Barcelona ahead of Alaves, they could only beat Alaves easily once. However, seeing the last week's consistency Alaves game much more stable than Barcelona, and may not be offset Alaves game of Barcelona. I expect no surprises that happen in this game.
