Bayern Munich closed in on a sixth-successive German Bundesliga title and sent Hamburg closer to a first relegation with a 6-0 rout of the beleaguered Dinos.
Heynckes said: "We have analysed our opponent". With Bayern playing the second leg of their Champions League draw with Besiktas on Wednesday, Heynckes could opt to rotate his squad again to give his players more rest.
Kimmich had been linked with a move to Manchester City to rejoin former Bayern boss Pep Guardiola but has poured cold water on such speculation by extending his stay in Munich by three years.
The veteran coach has certainly earned a contract extension, with Bayern now 20 points clear at the top of the league and only a few wins away from securing the Bundesliga title for a 28th time.
"It doesn't matter if we are 10, 15 or 20 points ahead, we need to keep going in the Bundesliga", said Arjen Robben. However, with Bayern already up 5-0 on aggregate, Bayern might not rest anyone and use a secondary squad in Champions League.
Franck Ribery broke away on the left before rounding goalkeeper Christian Mathenia to slot in the opener.
Four minutes later, Arjen Robben found Joshua Kimmich in space on the right and his cross was headed in by Lewandowski. The Polish worldwide struck again in the 19th minute, after a pinpoint long ball from Jerome Boateng had opened up the Hamburg defence.
Robben got in on the act in the 55th minute with a left-foot shot from the edge of the area and Ribery jinked his way through the Hamburg defence for his second and Bayern's fifth.
Lewandowski fired a spot-kick high five minutes later but rounded off his hat-trick with a stoppage-time penalty.
With 142 goals in competitive games, the Poland striker is Bayern's most prolific foreign player.
"He knows exactly who is in our sights and which players he would like to have".
Hamburg, the only ever-present team in the Bundesliga's 55-year history, are seven points adrift of Mainz who are in the relegation play-off spot.
In a bid to to stop the rot, Hamburg head coach Bernd Hollerbach brought on midfielder Vasilije Janjicic after just 24 minutes and the tactical switch stemmed the hosts' goal threat for the rest of the first half, but Bayern were comfortable.
"I wasn't satisfied with the way we lost".
Gregoritsch fired Augsburg in front on 26 minutes, heading in a deep cross from Caiuby at the far post.
The pole remained in the thick of things as he tripled the lead moments later when he tapped home an assist from David Alaba with 19 minutes played.
The home side continued to dominate and was rewarded with two goals in quick succession 10 minutes from time. Lewandowski made no mistake with his second attempt.
