Position and characteristics:
The 23-year-old is an attacking midfielder by trade but is not a typical No.10, as he prefers to get on the ball and make things happen, rather than just receive the ball and pick out his teammates with a pass.
For Hoffenheim, he is usually deployed in the No.10 role just behind the main striker, where he is given license to roam and he does exactly that as he is slowly becoming an expert in timing his late runs into the box.
For the national team at the Copa America he has been interestingly used as a centre-forward and that is a position that Liverpool have struggled to fill following the sale of Luis Suarez to Barcelona last summer and the injury problems to Daniel Sturridge.
