Having had Harry Arter under his tutelage for a few months now at Cardiff City, Neil Warnock has identified some concerns regarding the Irish international's approach to the game.
Speaking ahead of Cardiff's Premier League tie against Fulham this weekend, Warnock's men find themselves propping up the table.
Promoted from the EFL Championship with some style last season, the adjustment to a higher-level has not been as immediate as the English manager would have ideally liked.
Still looking to pick up their first win of the season, Warnock would happily deal without any unnecessary concerns. As he outlined himself in today's pre-match press conference, Arter's indiscipline is once such potential issue.
"You don't get players like [Harry] on loan unless there's something in their make-up," Warnock revealed this afternoon.
"Eddie [Howe, Bournemouth manager] did warn me ... he said he'd get booked in training. I tell him every day, during the game, at half-time, in the second-half. But I might as well keep my mouth shut."
Crediting Arter with putting in some solid performances since his loan move to the Welsh capital, Warnock nevertheless concluded: "Harry Arter does what he wants. You can't stop him."
Recently returning to the Republic of Ireland set up after a brief hiatus, Arter's indiscipline proved crucial in a 1-0 defeat to Wales in the UEFA Nations League.
Fouling Wales' Connor Roberts in the second-half, Harry Wilson's resulting free-kick brought about the only goal of the game for Ryan Giggs' side.
