The path to the 2020-21 Champions League final in Istanbul has now reached the knockout phase, and the draw for the round of 16 has thrown up some truly heavyweight encounters, with Barcelona vs. Paris Saint-Germain emerging as the outstanding tie with Lionel Messi and Neymar going head-to-head for a place in the quarterfinals.
Atletico Madrid vs. Chelsea will see Diego Costa return to Stamford Bridge for Diego Simeone's side, while Cristiano Ronaldo has the chance to play in Portugal once again following Juventus' pairing with FC Porto.
Reigning champions Bayern Munich will expect to overcome Lazio to reach the quarterfinals, while Real Madrid and Manchester City will believe they have a strong chance to progress at the expense of Atalanta and Borussia Monchengladbach, respectively. There is also an intriguing match-up between RB Leipzig and Liverpool, while reigning Europa League champions Sevilla take on Borussia Dortmund.
