The 31-year-old impressed in Burnley's 2-1 win at Cardiff City on Sunday, but Warnock thinks he should ignore thoughts of an England recall.
Joe Hart has been told to forget about earning a recall to the England squad despite producing a man-of-the-match display as Burnley beat Cardiff City in the Premier League.
The Clarets claimed their first away league win of the season at the Cardiff City Stadium thanks to goals from Johann Berg Gudmundsson and Sam Vokes.
Josh Murphy did level for the South Wales club, who suffered a fourth straight loss, but Vokes headed home the winner with 20 minutes to go.
