It probably says more about full back quality around but aside from Timber and Reece James, who actually is better than Dalot in the prem as a right back? City use Nunes and he is in no way a better right back. Liverpool have Frimpong who is a winger more than a full back who hasn't adapted to the league.
Livramento and Kayode are decent-good but I'm not sure they'd actually start regularly ahead of Dalot at this stage, similar level (but yes have the potential) for me. Who else? Cash? Porro? They aren't ahead of Dalot.
Which goes back to what I regularly say for right back... You need to spend serious money to actually upgrade, and there's no actual good option that is worth spending that money on to actually improve the position.
