#3 Ruben Dias
Ruben Dias costs 6.3 in FPL. He has scored 96 points so far this season. The Portuguese centre-back has been one of the best players in his position in the Premier League over the last 18 months.
He is an important player for City and is an important factor in their team conceding the least amount of league goals this season. In FPL, Dias is a valuable member as he gets clean sheets and goal contributions from set-pieces.
#2 Joao Cancelo
Joao Cancelo has always been a very talented fullback but the transformative effect that Pep Guardiola has had on him is quite something. He's among the best fullbacks in the world without even playing on his preferred side. His 5 G/A plus City's numerous clean sheets mean he is the second best performing defender in FPL with 121 points. He is available for 7.0.
#1 Trent Alexander-Arnold
Liverpool's Trent Alexander-Arnold is the best fullback in the world at the moment. He is the team's main creator from fullback and is often seen marauding down the right hand side to deliver pin-point crosses.
His 11 goal contributions in the league this term is the fifth highest of anyone in England. Not only that but his defensive work has also improved a lot. He's expensive at 8.4 but his output is worth the price. Trent is the best performing defender in FPL this season with 132 points.
