UEFA Champions League quarter-final facts

• FC Barcelona's victory at Paris Saint-Germain was their seventh in a row in the UEFA Champions League, three short of the competition record for successive wins held jointly by FC Bayern München and Real Madrid CF.

• The record for consecutive triumphs in a single season, however, is held by Barcelona themselves – nine in 2002/03. No other club has managed more than Barça's current run of seven, which began on matchday three with a 3-1 home victory against AFC Ajax, in one campaign.

• The first of Luis Suárez's two goals at the Parc des Princes was the 400th scored by Barcelona in the UEFA Champions League. Their grand total of 401 is surpassed only by Real Madrid, who have 436.

• FC Porto's opener in their 3-1 home win against Bayern – a penalty from Ricardo Quaresma – was the 200th goal conceded in the competition by the German club. Only Madrid (228) and Barcelona (201) have let in more.

• The goalless draw between Club Atlético de Madrid and Real Madrid was a rarity for the latter. It was only the sixth 0-0 scoreline in their 209 UEFA Champions League fixtures and their first in 78 games – since facing Olympiacos FC in Piraeus on matchday four of the 2007/08 season.

• The stalemate at the Vicente Calderón ended Madrid's run of five successive away wins in the competition – two short of the record – and also Atlético's perfect UEFA Champions League home form in 2014/15.

• The race is on to see whether Madrid's Iker Casillas or Barcelona's Xavi Hernández can become the first person to reach 150 UEFA Champions League appearances – perhaps this season – as both players took their tallies to a record-extending 147, Casillas completing the full 90 minutes against Atlético and Xavi coming off the bench in Paris.

• Cristiano Ronaldo and Lionel Messi remain locked together at the top of the all-time leading scorer rankings with 75 goals apiece after neither managed to find the net. It was the first matchday of 2014/15 on which both failed to score.

• Indeed, Messi has yet to register in the knockout phase as both he and Ronaldo remain on eight goals for this term's competition, one behind eliminated leading marksman Luiz Adriano of FC Shakhtar Donetsk. The last player other than Messi or Ronaldo to top the season's goal charts was AC Milan's Kaká in 2006/07.

• Madrid's Toni Kroos made his 50th appearance in the competition in the 0-0 draw at Atlético, his ninth outing for the Spanish club adding to the 41 he made for Bayern.

• Bayern's match at Porto was their 27th in the UEFA Champions League quarter-finals – one more than Manchester United FC, with whom they previously shared the record.

• The all-Madrid tie is the 23rd to be played between two clubs from the same nation in the UEFA Champions League knockout phase, finals included. It is the seventh tie involving two teams from Spain. Only England, with nine all-Premier League ties, has more.
