The two games in the Champions League round of 16 on Wednesday both feature favourites to go all the way in this season's competition. One is finely poised, the other... not so much.
Paris Saint-Germain nicked a one goal advantage late on in the home leg against Real Madrid but travel to the Santiago Bernabeu with plenty of work still to do.
Manchester City dispatched Sporting CP with ease in Lisbon to make the return fixture surely nothing more than a procession.
Here are some Opta facts ahead of both encounters to leave the mouth watering further ahead of the clash in Spain, and maybe even give the most optimistic of Sporting fans the slimmest glimmer of hope.
Real Madrid v Paris Saint-Germain
PSG were on top for much of the first leg in Paris, but it took a moment of genius from Kylian Mbappe in stoppage time to seal a 1-0 win.
That might be enough though as Madrid have been eliminated from nine of their last 10 knockout ties in the Champions League when losing the first leg, with the exception being a 3-2 aggregate victory over Wolfsburg in the 2015-16 quarter-finals.
However, PSG have been eliminated from three of their eight Champions League knockout ties when winning the first leg – only Barcelona (four) and Madrid (six) have been eliminated in this fashion more often.
Lionel Messi has failed to score in his last 695 minutes of action against Los Blancos in all competitions since scoring for Barcelona in May 2018. The Argentine had his penalty saved against them in the first leg, which was his fifth penalty failure in the Champions League (from 23 taken, excluding shoot-outs).
Mauricio Pochettino's men are winless in their last four away matches in the Champions League (D2 L2). They last had a longer run without a win on the road in the competition between September 2000 and October 2012 (10 games).
Karim Benzema, meanwhile, has scored 12 goals in his last 11 Champions League home games for Madrid. Overall, he has netted 64 goals for the Spanish side in the competition, behind only Cristiano Ronaldo (105) and Raul (66).
Mbappe, who has been linked with a move to Madrid and may well be an injury doubt for Wednesday, has been directly involved in 18 goals in his last 13 appearances in the Champions League, scoring 13 and assisting a further five.
Manchester City v Sporting CP
City eased to a 5-0 win in Portugal, the joint-biggest winning margin away from home in the knockout stages in Champions League history. The largest first-leg deficit to be overturned in the competition is four goals (PSG 4-0, Barcelona 6-1 in 2016-17).
Pep Guardiola's team have won their last six home matches in the knockout stages of the Champions League, and could tie a record that has been reached on five occasions previously (Bayern Munich – April 2002, Milan – April 2006, Manchester United – March 2009, Bayern – February 2017 and Madrid – February 2018).
Kevin De Bruyne – who scored twice in a 4-1 win over Manchester United on Sunday – could make his 50th Champions League appearance for City. The Belgian has been directly involved in 27 goals in his previous 49 (10 goals and 17 assists).
Riyad Mahrez has scored six Champions League goals this season and needs one more to set a record for most goals in a single season in the competition by a City player.
Sporting, on the other hand, have lost all three of their matches in the knockout rounds of the Champions League, conceding 17 goals in total (5.7 per game).
Ruben Amorim's side have failed to keep a clean sheet in any of their last 13 away matches in the Champions League, conceding 31 goals in the process (2.4 per game). This is already the longest run of away matches without a clean sheet by a Portuguese side in the competition.
