Liverpool fans may have seen very little of 22-year-old defender Sepp van den Berg since he joined in 2019, but should they let the youngster go? The Dutch under-21 international has only made four first-team appearances for the Reds since signing from PEC Zwolle, having had loan spells at Preston North End, Schalke and last season with Mainz. Van den Berg was a regular starter for the German side last campaign, featuring 36 times across all competitions and scoring three goals.
