PER CURIAM: *

Gustavo Villarreal appeals the 188-month sentence following his guilty plea conviction for conspiracy to possess with intent to distribute over five kilograms of cocaine. He contends that he was entitled to a downward departure for substantial assistance and that the Government’s failure to file a motion pursuant to Section 5K1.1 of the Sentencing Guidelines revealed bad faith. Villarreal also contends that his within-Guidelines sentence is unreasonable.

Villarreal was not entitled to a Section 5K1.1 motion. He has neither established that the Government negotiated away its discretion to choose not to file a motion, nor that the Government’s failure to file a motion was based on an unconstitutional motive. See United States v. Aderholt, 87 F.3d 740, 742-43 (5th Cir. 1996). Villarreal has not even shown that he did actually provide substantial assistance. Id.

Villarreal’s unreasonable-sentence argument also fails. Villarreal has not established procedural error in the district court’s sentencing process. See Gall v. United States, — U.S. -, 128 S.Ct. 586, 597, 169 L.Ed.2d 445 (2007). Nor has he established that the district court abused its discretion by imposing a sentence within the applicable Guidelines *340 range, which is presumptively reasonable. See United States v. Cisneros-Gutierrez, 517 F.3d 751, 766 (5th Cir. 2008).

The judgment of the district court is AFFIRMED.
