Steve Kean praised the 'excellent' Jordan Rhodes after Blackburn Rovers beat Bristol City 5-3 to move top of the Championship, while Derek McInnes was left to bemoan his side's defending.
Rhodes scored twice at Ashton Gate, while Nuno Gomes, Ruben Rochina and Scott Dann also found the target in a thrilling encounter.
Albert Adomah had put Bristol City in front and Blackburn also conceded goals to Stephen Pearson and Sam Baldock, leaving Kean to admit his defence needed work.
But Kean had nothing but plaudits for Rhodes, saying: "It wasn't just the way he took his goals. I don't think he gave the ball away all afternoon and his link-up play was excellent.
"The great thing when you buy a quality striker is that when he gets a chance you expect him to score.
"But there is much more to Jordan's game than finding the back of the net and he is open to plenty of improvement at such a young age.
"It's great to be top of the Championship, even this early in the season, but it goes without saying that we need to improve defensively.
"We should have more points because we scored three at Leeds and only got a draw. It's our goals-against column that needs working on.
"But tonight we can enjoy an excellent win over a very good Bristol City team, who will take a lot of points home and away this season."
McInnes felt his Bristol City team did not make Blackburn work hard enough, while he is now looking to bounce back against bottom club Peterborough on Tuesday.
He said: "We had to work for our goals, but each of Blackburn's should have been prevented.
"I was very disappointed in that aspect of our play, particularly as there were so many positives going forward.
"Albert Adomah caused them so many problems. We felt we could score goals against Blackburn, but I never envisaged us conceding five.
"It's important we get back to winning ways quickly at Peterborough on Tuesday, It's no secret that I am looking to sign a new centre-back, but we defend as a team and there were some bad decisions made today."
