Aguero is, IMO, definitely not past his prime. He'll contribute big time this year towards our title winning campaign.
Aguero does need to adapt his play style though - counter-pressing is a must in Pep's system; in the past, Aguero did not consistently participate in pressing, but this year, I see him immediately pressing after a turn over.
Although I think that Jesus fits Pep's style better - better at ball control/linking in tight spaces - Kun is more than adequate, is not a trouble maker, and clearly wants to remain in our side.
I wouldn't trade Kun for any PL striker.
==============
Perhaps the biggest missing element in our team is an attacker, able to dribble past defenders to create chances from nowhere. Sane, on the wing, can beat players for pace; Sterling, on the wing can beat players for pace and sometimes for dribbling skill; but centrally, we don't have anyone.
Teams will pack it in on us, and although we'll get plenty of good crosses from our full/wing-backs, the benefit from this is dampened because our strikers aren't massively dominant in the air and because ground-crosses will be cut off frequently by packed in defenses.
Someone like Hazzard or Suarez would massively improve our team especially against packed defenses. But this sort of player will likely be signed only next year.
