It'd almost be quite disappointing if we have to wait another year before he plays another match, if not in the league cup. Of course with Van Dijk a nailed on starter, and Gomez/Lovren/Matip all involved, it won't be easy for him to find much game time anywhere, he's shown his maturity massively tonight.
Would also be interesting to see him play a first team game at right back, if tonight was anything to go by he might look comfortable.
