Unai Emery has admitted Jurgen Klopp's Liverpool side are unrecognisable from the team he beat in the Europa League final the first time he locked horns with the Reds back in 2016.
Then in charge of Sevilla, the Spaniard led his side to a 3-1 victory despite trailing to a Daniel Sturridge strike at half-time, with Liverpool failing to qualify for the Champions League as a result.
However, the Reds have qualified for Europe's elite tournament every season since then and, having beaten Emery's Villarreal team 2-0 at Anfield on Wednesday night are on the verge of reaching a third final in five years.
