Even if you believe that to be Gerrard's peak (many would argue you otherwise) what he was doing, at ages younger than De Bruyne is right now, is in another class altogether. Gerrard was a forerunner in the CL, and although rough around the edges (I won't argue his play was as refined as De Bruyne's) he was a genuine force as an individual. You can throw positional accusations at him, but from the right side of midfield, there's no chance he was inferior to De Bruyne, for what he lacked in refinery, he made up in both goals and dynamism. We've yet to see what De Bruyne is actually made of when the chips are truly down for his team and whether he, too, has that force of presence to turn lost games against top-class opposition into winning ones.
You're basing a lot of your views on De Bruyne on league football alone, that's tricky when you're putting him up against someone who was a CL star performer. De Bruyne has a long way to go to be seen as such, and until he does, you're comparing two different tiers of football entirely and concluding them as one, which will always put De Bruyne in a poorer light.
It would be at least understandable if De Bruyne was hitting Henry, C.Ronaldo or even Bale levels in the league, but he's not - he looks very, very good in a very, very good team but nobody is going to put it forth as a season of a lifetime or for the ages as they would with the above.
I really rate De Bruyne, but there are tiers and context you can't just throw out amidst a rampant domestic campaign for the team, not just the player. De Bruyne doesn't look a level above his team-mates - he looks like one key component next to another in Silva, next to others in Aguero, Sane and Sterling as well as Jesus. They've all shared the limelight at times, none of them have been transcendent to the degrees of the aforementioned, or how Gerrard used to be.
He may have been 'Stevie Me' but that was with good reason given he bailed his team out on countless occasions.
Exactly, three different teams of quality with three different players of quality, all going at it in the same time period. De Bruyne has nothing like that opposing quality to contend with.
