Before GRUENDER, MURPHY, and BENTON, Circuit Judges.
                         ____________

PER CURIAM.

      Mark Lembo appeals after he pleaded guilty to a drug offense and the district
     1
court sentenced him to 216 months in prison. His appellate counsel has moved for

         1
        The Honorable Leonard T. Strand, Chief Judge, United States District Court
for the Northern District of Iowa.
leave to withdraw and has filed a brief under Anders v. California, 

(1967), suggesting that—as a result of trial counsel’s ineffective assistance—Lembo’s
guilty plea was not knowing and voluntary.

       We decline to consider any ineffective-assistance claim on direct appeal. See
United States v. Ramirez-Hernandez, 

, 826-27 (8th Cir. 2006) (stating
that ineffective-assistance claims are usually best litigated in collateral proceedings,
where the record can be properly developed). We also conclude that any direct
challenge to Lembo’s guilty plea, as not knowing and voluntary, is not cognizable on
direct appeal because Lembo did not move in the district court to withdraw his guilty
plea. See United States v. Foy, 

, 1033-34 (8th Cir. 2010) (noting that,
to the extent the defendant presented an argument to establish that his plea was
unknowing or involuntary, such a claim would not be cognizable on direct appeal
where he failed to move in the district court to withdraw his guilty plea). In addition,
having independently reviewed the record pursuant to Penson v. Ohio, 

(1988), we find no nonfrivolous issues for appeal. Accordingly, we grant counsel
leave to withdraw, and we affirm.
