#2 Lionel Messi vs Virgil van Dijk/Andrew Robertson
Lionel Messi is in a sublime run of form this season, scoring 46 and creating 18 goals. The Argentine looks in the mood to win the Champions League this season, influencing the games on his own.
The Liverpool defence comprising of Virgil van Dijk and Andrew Roberson has been rock-solid this season. The combination of van Dijk's colossal defending and Robertson's attacking shifts have been prime ingredients of Liverpool's success.
Messi makes world-class defenders look like amateurs, and the Reds' shielding duo face an arduous task of containing him. Virgil van Dijk was asked about the prospect of facing the Argentine magician and he responded by saying:
“I think he is the best player in the world. But you see how we play and how we defend. We don’t defend one v one, we defend all together and we attack all together as well so we will see. We will be ready."
The onus of patrolling Barca's skipper lies significantly on the Robertson-VVD partnership. Van Dijk will require ample support from his left-sided partner. Keeping tabs on the five-time Balon d'Or winner is a litmus test for the Scottish left-back's defensive discipline.
Facing Messi is the biggest challenge for Robertson in his Liverpool career so far, and it presents an opportunity to display his positioning awareness and assert his status as one of the world's best full-backs.
