THEY’VE won seven games in a row and are the AFL's highest scorers, but Adelaide believe their current form won't win them a final.

The third-placed Crows host Collingwood on Saturday night with assistant coach David Teague saying there's still much improvement needed at his club.

"We don't think the way we're playing now is going to be good enough at the end of the year," Teague told reporters on Friday.

"We think we have got some areas to improve and we're going to need to improve on those.

"It's a whole game thing. Some of our defence we want to improve, some of our offence - they are just small things we want to tweak.

"We won't go into the exact details but we have got quite a few areas we want to improve on.

"Having said that, we're doing a lot right at the moment too."

Adelaide expect Collingwood, in 11th spot and three wins outside the top eight, to offer a stern test as the Crows mark the 300th AFL game milestone of onballer Scott Thompson on Saturday night.

"Their pressure is probably one thing that I have noticed ... it has been really good lately," Teague said of the Magpies, who have won three consecutive matches.

"Any team that brings good pressure asks a good question of the opposition. And it's one we're looking forward to answer this week.

"We feel that the pressure games are going to be finals-type games so we want opposition to bring pressure and we want to be able to stand up and handle it and we'll find that out tomorrow night."
