I think Aaaron Wan-Bissaka is the best right back in FIFA 20 and i give you a taste why i think so. First of all, when FIFA 20 was released with EA Early Access i was lucky to get his normal gold card in my very first pack! At this time he had a price rang of 10,000 coins. I was patient and waited until EA changed his price range and sold him for 30,000 coins and bought his Ones To Watch card for 44,750 coins. So, i technically paid just 16,250 coins for him which i think is a very good deal. I realised that in FIFA 20 it is very important that your RB and LB defenders have a high workrate for defending, because they will stay in a better defense. Aaron Wan-Bissaka has a really good pace above average combined with a stunning Physicality in-game! So, Pace, Defending and Physicality are a definitely YES from me! The Negavtive things are his bad short passing. (On his card 70, feels like 60 or 55 for me) and his horrible Crossing.
At last but not least i think you can not do anything wrong if you buy him for 35,000 - 45,000 coins because you never know if he gets an upgrade or not. If he gets one his price will go up high and if he doesnt get one you can sell him and lose i think around 5,000 to 8,000 coins. Thats okay i guess.
I am sorry if my english isnt all correct because my native language is german. Please rate my review and let me know if you liked him if you tried him.
