Adelaide captain Taylor Walker isn't blaming his foot injury for his form slump.

While he's been unable to train fully recently because of the injury, Walker says it's not the reason for his below-par output.

"I set high standards on myself, obviously I'm not playing to that standard at the moment," Walker told reporters on Monday.

The key forward has kicked 14 goals this season and is averaging just over 12 disposals a game.

He started strongly against Geelong on Friday night, kicking two goals in the first quarter.

Walker was confident an increase in his training loads would lift his form.

"I obviously had a bit of a sore foot so I couldn't consistently train but I'm back out there and enjoying being back out there," he said.

"(My) form is on the way up.

"I know it's not far around the corner.

"I think the beauty of playing AFL, you control your own form and the pathway that you want to go. So I have been working hard, as much as I can behind the scenes, and I'll continue to do that."

Adelaide has four wins and four losses after a tough opening eight rounds.

The Crows are one of the highest scoring teams in the competition, but have struggled to stop the opposition scoring. They are also averaging eight fewer forward 50m entries than their opposition.

Walker said team defence and better supply from the midfield were the keys to reversing the trend.

“We had our game review earlier today and ‘Pykey’ (coach Don Pyke) made it really clear what we need to work on,” he said.

“We’re doing some really good things in our attack, but with our team defence at the moment we’re allowing too many inside 50ms, which puts a lot of pressure on our defenders.

“We’re just not winning enough footy through the midfield to get it in our half.”

Walker described his team’s form as inconsistent.

"It's just a reflection of our football at the moment," he said of the win-loss count.

"We have been playing some inconsistent footy so we're crystal clear where we're at.

"We have been able to do. It's just doing it for longer."
