The mental effort of Carlton has come under fire following its 65-point loss to Brisbane on Saturday.

Nick Dal Santo, speaking on SEN said the lowly Blues have talent but lack the required "mindset and application".

“Five players from the Blues had one or no kicks at half-time,” Dal Santo told SEN Breakfast on Monday.

“Everyone comes into this competition with ability, the rest of it is mindset and application and just digging in week after week.

“Massive mental concerns with that, application.”

Three Carlton players failed to register a tackle whilst playing over 75 per cent of game time in the defeat.

St. Kilda champion Danny Frawley said on SEN this morning the struggling Blues need to bring "a little bit of effort" and "turn the heat around somehow".

Frawley added "they need to get off the ropes and start swinging."

Carlton will look to apply this effort when it takes on St. Kilda Friday night at Etihad Stadium, a potentially winnable game against another struggling team.
