Paul Merson is unsure over whether Trent Alexander-Arnold will be able to carry on in his new inverted full-back role against bigger teams.
Alexander-Arnold's new role was first seen during Liverpool's 2-2 draw with Premier League leaders Arsenal and then it was displayed to a greater effect in the 6-1 thrashing of Leeds United.
The 24-year-old is still deployed as a right-back on the team sheet, but he is now seen roaming into the middle of the pitch to get on the ball and create chances with his sublime passing abilities.
