Mauricio Pellegrino has vowed to create problems for Liverpool when he visits his former club for the first time as Southampton manager.
Pellegrino, the former Argentina international, spent time at Anfield in both playing and coaching capacities alongside Rafael Benitez, before going it alone as a manager in his own right.
The 46-year-old has managed in both his homeland and La Liga - with Valencia and then Alaves - before replacing Claude Puel at St Mary's in the summer.
It has not been an easy transition to life in the Premier League for Pellegrino - with his side struggling for both points and goals - and he will head to Anfield on Saturday in need of a morale-boosting result.
