Trent Alexander-Arnold had really performed brilliantly as a right full back for Liverpool until last two seasons when his performances diminished and lost form, recall his ability to overlap along the flank and his ability to cross ball to his main striker was topnotch just like Roberson doing the same job at the left flank, though Trent Alexander-Arnold might also has his weak point defensively well Gareth Southgate played him in midfield in their recent matches for England personally I think he only play against minnow countries e.g Malta   until when England play top football countries and prove him himself in those matches that is when I will rate him.
