Lorenzo Verduzco-Mendoza pleaded guilty to one count of conspiracy to possess with intent to distribute more than 500 grams of methamphetamine. He appeals the denial of his motion to withdraw his guilty plea. We find no error in the district court’s application of the factors to be considered in deciding whether to grant a motion to withdraw. See United States v. Carr, 740 F.2d 339, 343-44 (5th Cir. 1984). Verduzco-Mendoza’s assertions of innocence were not made under oath, and he has provided no good justification for his delay in seeking to withdraw his guilty plea. See id.; see also United States v. Clark, 931 F.2d 292, 294-95 (5th Cir. 1991). His plea was knowingly and voluntarily entered and he enjoyed the close assistance of counsel. See Carr, 740 F.2d at 343-44. The district court’s finding that Verduzco-Mendoza’s motion to withdraw his guilty plea was an attempt to manipulate the system was not clearly erroneous, and the court did not abuse its discretion in denying the motion. See id. at 343-45; see also United States v. Powell, 354 F.3d 362, 370 (5th Cir. 2003).

AFFIRMED.
