VIDEO: Iker Casillas, Marco Verratti - The Ones to Watch in the UEFA Champions League

The UEFA Champions League Round of 16 resumes on Wednesday with two more potential thrillers.

But who will rise up above the rest and be crowned the UEFA Champions League Player of the Week, sponsored by Banco Santander?

FC Porto host Roma hoping to overturn a 2-1 defeat in the Italian capital last month, and will look to former UEFA Champions League-winner Iker Casillas for inspiration.

The former Real Madrid man holds the all-time record for the most clean sheets in the competition, with a staggering 59 of them, and will be hoping for yet another shut-out to help send his side through.

PSG, meanwhile, will look to finish the job after an impressive 2-0 victory over Manchester United at Old Trafford in their first-leg.

Midfielder Marco Verratti will have a key role to play – he was sensational in their victory in Manchester and has added a bite to his cultured midfield playmaking, averaging four tackles per game in the UCL this season.

Voting for Player of the Week opens on Thursday.
