Walker or Cancelo? Who is the best right back? Well, it depends on your needs. Kyle Walker defends better but Cancelo is the right choice if you want someone good on the attack and able to assists his teammates.
Trent Alexander-Arnold is widely used by the community but Ricardo Pereira is clearly better than him. Players from popular clubs are usually more expensive but in this case, it won’t help you in the field.
Bellerín is the fastest Premier League right-back but he is also the weakest one. Besides that, he has low defensive work rate, which is not quite convenient for someone that is supposed to defend. Yedlin can be compared to him, especially because of his pace, but is not a quality choice for the defence either. In our opinion, Aaron Wan-Bissaka is a better option. He has the lowest passing stat but at least he gives security to your back line.
Azpilicueta reminds us Zabaleta of past years: slow but a wall in the defence. He is a decent choice if you don’t want him to attack. You can also take a look at Aurier and Sidibé, cheap and balanced right backs.
