Its not wide eyed belief. Its rational thought. Ive heard numerous times form City fans on this forum, Odegaard would be the perfect replacement for KDB. Ive heard some City fans mention Saka as a perfect replacement for Mahrez. Saliba is a rolls royce centre half and could cost more than what you would pay for Gvardiol. Martinelli is another rolls royce.
Even if its not in the very short term (this year). Our players and young enough and on long enough contracts to wait out your current cycle. Two years from now, Pep, KDB, Gundogan, Bernardo, Walker, Mahrez will be gone, Stones will be 31. Although the big ones are Pep and KDB - replacing these two is nigh on impossible. There is also a dark cloud that looms over you, that could turn into a hurricane in a time the spearhead of your current success has left.
You wont have it your way forever as football has always been cyclical. Man United in the 1990's and early 2000's. Liverpool in the 1980's. Barcelona in the 2010's. Your cycle too has a lifespan.
Your one sentimental Kompany appointment away from sliding down the ladder, just like United did when they got it wrong giving Moyes the job to replace Fergie - and have spent the last 10 years paying for it.
Not trying to wind anyone up, all im saying, is football can be very volatile when key figures leave a football club.
