Luis Suarez scored twice in his return for Barcelona as they made short work of Valencia in a 5-2 win at the Camp Nou with an injured Lionel Messi looking on from the sidelines.
The hosts raced out to a 2-0 lead with teenager Ansu Fati scoring the first goal and setting up the second for new arrival Frenkie de Jong inside of 10 minutes.
Kevin Gameiro finished off a nice team move to pull one back for Valencia before half-time, with the referee consulting VAR to award the goal after the linesman's flag had initially gone up for offside.

Gerard Pique restored Barca's two-goal lead shortly after the restart, pouncing on a rebound from a well-hit Antoine Griezmann shot and tapping it home.
Substitute Suarez, back from a spell on the sidelines with an injury, produced a moment of brilliance shortly after coming on, faking a pass to his right and then curling a shot past Jasper Cillessen at the near post to make it 4-1.
The Uruguay international then added a second at the near post, picking up a loose ball in the penalty area and once again curling it just out of the reach of Cillessen.
Valencia scored a meaningless late goal through Maxi Gomez to reach the final scoreline as Barca eased to three important points on a day that table-toppers Atletico Madrid lost.
Next up for Barcelona is their Champions League group stage opener against Borussia Dortmund on Sept. 17, a match which Messi is also expected to miss.
