The four matches in the first legs of this season's UEFA Champions League quarterfinals ties have all been action-packed goal fests so far.
The most impactful game was Arsenal hammering three past Real Madrid, courtesy of Declan Rice's stunning free-kick brace. Barcelona were imperious and Paris Saint-Germain were confident in their wins, which put one foot in the door of the semifinals. Bayern Munich vs Inter Milan is more evenly poised than the rest but there is also enough chance of teams turning the tide next. What are Champions Leagues second legs, if not the possibility of incredible comebacks?
ESPN's By The Numbers brings you the best of the mid-week stats from the UCL:

Rice is only the third player in the last 15 UCL seasons with multiple direct free-kick goals in a game and the fifth player to score 2 direct free kick goals in the same Champions League match. The others are Rivaldo (BAR) in 2000 vs AC Milan, Cristiano Ronaldo (RMA) in 2009 vs Zurich, Neymar (PSG) in 2018 vs Red Star, and Hakim Ziyech (GAL) in 2023 vs Man United

Raphinha (12) and Robert Lewandowski (11) are the first pair of teammates to score 10+ goals in a UCL season since Mohamed Salah, Roberto Firmino and Sadio Mané all scored 10 goals in 2017-18 for Liverpool.

Khvicha Kvaratskhelia has as many UCL KO stage goals (2) with PSG as Neymar, but in far fewer games (Neymar 13, Kvaratskhelia 5)
3
One small hope for Aston Villa in the second leg...PSG has failed to advance in the UCL KO Stage three times after winning the first leg in their tie by more than 2 goals - more than any other team in UCL history.
Indeed, two of the three times PSG failed to advance after winning the first leg by more than 2 goals were against English teams.
