If you need an op cheap left back, you can definitely get 87 Alex Telles. I used him with a shadow, so his pace was basically perfect. Even though he doesn't have the highest strength, he could body some wingers off the ball pretty well, and get the ball without much effort. He is pretty solid, the only issue is that he sometimes (rarely) gets caught off position and gives the opposite winger lots of space. His long passings are also really good.
Strength (no need for anchor)
Brazilian Link (Neymar, Miranda, Juan Jesus)
Rarely off position
Liga NOS (if he actually joins Chelsea he will surely be the most used left back of Fifa 21)
