Little late in commenting this however: a splendid performance by the Greek with two assists for Salah and co against the Bees. Though a very forgettable 45 minutes in the Europa League with two goals conceded (so he's not the best of leaders partly from an armchair supporters perspective). I would rate him if he could make the tackles we know he is capable of, I imagine he makes more in training than using his good concentration for interceptions and tackles in the cup and Premiership.
His inclusion in Liverpool's first team does make me wonder, would half the promising players we sign fair better at other clubs south and west of Germany? Kostas shouldn't really be playing for us in that sense...
