Saracens secured a home semi-final against Northampton with a 23-14 win over Bath which also saw them top the table.
Saracens have been criticised for not scoring that many tires but have statistically been the better side and have used their dominant lineout and scrum to win territory and ultimately the game - a game plan that they will not change.
"Saracens will always take some beating," said Dean Ryan. They are so efficient in every single area. The key thing is what happens when they get a bit unstructured. We saw a little bit of that today when they rolled on the bench and it got a little bit messy.
"They don't look natural in that environment and they have to ask the question on how do they take the next step up. Their efficiency at Premiership level puts them right up there in the mix but they are desperate for European success and they need to find that balance.
"They have made some big signings over the summer with Billy Vunipola and James Johnston - some real meat on the bones coming here. They need to get that mix of real power and efficiency in all areas.
"But for Northampton they won't change, it is probably enough - those efficiencies around the breakdown, the kick-chase, the driving line out and the set piece - all those things that we have been saying about them is enough in the Premiership. Anyone who comes here has to find an answer."
However Will Greenwood believes that Northampton have the powergame to match Sarries after watching them fight back from 22-5 down to quins to narrowly lose 22-19.
"The thing about Northampton is that today Quins beat them by pace, pace and more pace," explained Greenwood.
"Saints came back into the game with the power. I think they have the ability to come to Saracens and match Sarries power.
"It is going to be interesting you have to give the advantage to Saracens and their home advantage. However the way they have gone back to just being efficient, box kick and defensive just invites a side like Northampton, who are big lumps and can really match them, to have a go."
