The Mexican winger had a starring run in Villarreal's win over Valencia Sunday, netting a goal and adding an assist in a 3-0 victory.
The Mexican winger set up his club's first goal and then atoned for a missed penalty by netting a brace in the second half.
Ikechukwu Uche tucked away a cross from Dos Santos 17 minutes into the match, and Hernán Pérez made it 2-0 after 22 minutes.
Just after the break, Uche won a penalty that Dos Santos failed to convert, but he made amends moments later from a corner and had his team up 3-0.
Ricardo Costa pulled one back for Valencia in the 63rd minute, but Dos Santos added his second of the night in the 84th minute to lock up all three points for Villarreal.
