IMO this is getting things completely the wrong way round.
What Pep managed to pull off this season is incredible precisely because this side is fatally flawed by the lack of a striker.
This might end up our most successful year on paper, but the reality is we've not been great. The quality of our football compared to 2018 and 2019 is miles off.
What are we, 35 goals down on a good season? Drawn and lost 10 games? So many of our wins are by 1 goal, real nail biting finishes.
It's a triumph of Guardiola's ability to adapt and overcome problems that he's managed his way around it, but the answer is not to make that disadvantage permanent...it's to fix the problem. Get a striker. Score 100+ goals in the league and stop needing to rely on the defence playing out of their skin.
