In terms of the development of the Manchester City squad, the deal to sign Kalvin Phillips is a one-in, one-out kind of transfer, with the England international essentially taking the place of Fernandinho.
The deal to sign Erling Haaland is fixing a (relative) problem position for City, but Pep Guardiola is happy with the size and depth of his squad and the club's transfer business these days is generally replacing or refreshing, rather than any major cosmetic surgery.
Fernandinho's decision to leave the club at the end of last season left a place in midfield and while 18-year-old Romeo Lavia is highly thought of, City felt they needed a more experienced player to replace the iconic club captain.
