Suarez, who scored Barca's third goal with an outstanding solo run and finish, was hurt towards the end of the victory, in which Lionel Messi scored a glorious hat-trick. The Argentinian lined up a free kick from about 25 yards out. A single consolation goal for the hosts came from Loren Morón eight minutes from time, just three minutes before Messi's latest stroke of genius.
Lionel Messi netted the first goal in the 18th minute from a superb free-kick to give Barcelona the lead.
They also only registered three more shots than their opponents - 16 compared to Betis' 13 - although only three of the home side's efforts hit the target.
"We were playing against a team that treats the ball very well but the coach read the game perfectly from a tactical point of view".
"Our opponents suffer because of Messi, to a certain degree, but they also recognize the player he is and enjoy him", Valverde explained in his post-match press conference, via Ruptly. "Worse things have happened".
"The boss read the game very well, tactically it was ideal and we didn't suffer, just the opposite".
Suarez opened scoring in the second half, netting a pass from Gerard Pique in the 63rd minute.
An injury assessment has confirmed Suarez will miss between 10-15 days.
Messi, who scored twice in Barca's 5-1 win over Olympique Lyonnais in the Champions League on Wednesday, now has 29 goals in 26 La Liga appearances and 39 strikes in all competitions.
