Football Manager 2016: 20 Left Backs You Need To Sign

4. Guilherme Arana

Brazilian #5. The youngest man on the list is probably one of the players you should sign regardless of your needs. Guilherme Arana is worth just 97k, yet he genuinely has the potential to become a world superstar. It's a no-brainer, just sign him immediately. The 17-year-old will have to wait until his next birthday to transfer across, but that's no problem. He'll spend a couple of years on loan and training in your reserve team, but ploughing some effort into nurturing Arana will pay-off big-time.
