Right Back. Liverpool. TRENT ALEXANDER-ARNOLD. 8. Clearly the plan to target the youngster early. He stood up well and kept his composure, helped slightly by Sane who rushed everything. The winger was visibly frustrated at the end, meaning a job well done for TAA. He was determined not to have a repeat of his performance against United. Overall an incredible showing from a 19-year-old playing in a Champions League quarter final.
