He can play in multiple positions
After moving to Gladbach in 2018, Plea has more often than not been used as a central striker. His ability to play right across the front three is likely to be one of the main reasons why United are interested in him.
The 27-year-old bagged 15 goals during his first season in Germany. He has only scored nine this campaign, though, although he is a creative outlet, having provided eight assists as well.
