Right Back - Aaron Wan-Bissaka
Liverpool loaned off Clyne in the winter transfer window, which seems to be an erroneous decision. The Liverpool squad looks weak in defense and Clyne would have provided a good option for Jurgen Klopp, but Clyne had lost a lot of his potential after his injury last season.
Trent Alexander Arnold is a good right back, but there is no cover for him if he gets injured. Gomez can fill in that role, but he has established himself as Liverpool's first choice center back. Aaron Wan-Bissaka of Crystal Palace can be a great fit for the Reds.
He has been making a name for himself at Palace by being part of their solid defense; he also has been rising through the England setup quite rapidly with rumors that he will be called up for the next internationals.
He can be a great addition to Liverpool as a backup for now and can maybe even guarantee a starting place for himself in the future under Klopp.
