Agree with that. We've got Tierney, Pepe, Saka, ESR, Partey, Gabriel, and maybe Saliba. Leno at a stretch. The squad we build around them should fill in the gaps, cover their weaknesses, and amplify their strengths. This means have alternatives that are actual alternatives, and it also means building our own squad with our own game - not necessarily trying to copy other teams.
Hakimi and Chambers sounds like an excellent duo for right back. Willock would be a great option to have, but if you can convert him into a more perfect starting player, I'd do that.
