Starting at 82 overall with 87 Sprint Speed, 81 Ball Control and 82 Crossing, Reguilon will be able to slide straight into your starting lineup and pose a serious attacking threat.
Alphonso Davies (OVR 81 - POT 89)
click to enlarge + 7Alphonso Davies has proven a worthy successor to David Alaba at left back for Bayern Munich. With the Austrian veteran playing most of his football at centre back, Davies has become a regular starter for the German giants.
On FIFA 21 Davies has a phenomenal potential of 89 and already possesses acceleration and sprint speed stats of 96. Combined with his 85 Agility, the young Canadian will prove a tricky customer on the left flank.
Renan Lodi (OVR 81 - POT 86)

At 22-years-old, Lodi is ready for first team action from the outset - with 85 Acceleration, 81 Ball Control and 82 Crossing, the Brazilian fullback offers a serious threat going forward.
Theo Hernandez (OVR 81 - POT 86)

Standing at six foot tall, Hernandez has 93 Sprint Speed, 80 Crossing, 79 Dribbling and 79 Sliding Tackle ratings - an all-rounder if ever we saw one!
Ben Chilwell (OVR 81 - POT 85)
click to enlarge + 7After four brilliant years at Leicester, Chilwell moved on to the next chapter in his career in the summer with his move to Chelsea worth over £45 million.
Chilwell might not be the fastest left back around, but he will run all day with 88 Stamina.
Angelino (OVR 81 - POT 85)
click to enlarge + 7After moving to Man City back in July 2019, Angelino was loaned out to RB Leipzig the following January until the end of the 2020/21 campaign.
This means you’ll have to wait until the end of your first season to sign him, but with 86 Crossing, 85 Balance and 85 Stamina, he could well be worth the wait.
Pervis Estupinan (OVR 79 - POT 86)
click to enlarge + 7Pervis Estupinan has been part of the Watford set up since back in 2017. After several loans, Watford sold the young left back to Villarreal this summer for just over £14 million.
However, if you want to utilise Estupinan’s straight away, you can shell out over £70 million to pay his release clause. Better off waiting we reckon.
