Cristiano Ronaldo is playing in his native Portugal with Juventus this week for the first time since joining the Italian giants in 2018.
The 36-year-old attacker is set to line-up for the Old Lady as they take on Porto in the Champions League last-16, first-leg clash at the Estadio do Dragao.
Juventus' hopes of a 10th consecutive Serie A title have faltered of late – their 1-0 defeat at Napoli on Saturday left Andrea Pirlo's side eight points adrift of leaders Inter Milan, albeit with a game in hand.
This defeat will not bring us down," insisted Ronaldo after the match. "Let's raise our heads and think about the Champions League."
Porto, meanwhile, have drawn their last four games domestically and are 10 points behind league leaders Sporting Lisbon.
Ronaldo faces a Portuguese team for the first time since 2016 when with Real Madrid he beat his former club Sporting Lisbon 2-1.
But his last Champions League visit to the Estadio do Dragao dates back to a quarter-final, second leg in April 2009 with Manchester United, when he scored the only goal of the second leg – a thunderous finish from 30 metres out – to earn his team a 3-2 aggregate victory. United would go on to lose 2-0 to Barcelona in that season's final in Rome.
Juventus finished top their Champions League Group G, level with Barca having taken 15 points from a possible 18.
Porto, meanwhile, were second in Group C, finishing three points behind table-toppers Manchester City having won four and drawing one of their six games.
