I think the stockpiling of multiple expensive players per position is more a City policy than a Pep-specific thing.
Since 2012/13:
- Javi Garcia
- Nastasic
- Maicon
- Richard Wright
- Demichelis
- Mangala
- Caballero
- Sagna
- Otamendi
- Delph (Don't remember him playing CM, only LB... knock off £10m if you like)
- Stones
- Bravo
- Zinchenko
- Laporte
- Mendy
- Walker
- Ederson
- Danilo
- Cancelo
- Angelino
- Steffen
- Dias
- Ake
Total cost of c. £580m. In the same period, United (high spenders in their own right) spent £290m on defence.
The point is that Manchester City are buying multiple £50m+ players per position, which I don't believe any other team in the world have done before. If United had signed Stones for 50m and he performed so badly for 3-4 years, we'd have had to rely on him (or sell him within a season) because of how much was spent in defence. City just bought another 3 CBs (costing £160m) whilst keeping Stones (a £50m player) as backup, and their performances didn't suffer as a result.
Re: Gabriel Jesus - I think he's a good striker who would look good at United with his work rate and our playstyle. Likewise I think he could make a good replacement for Jamie Vardy at Leicester.
PS. Sorry for going off-topic but it's something I feel worth recognising.
