City-Chelsea: eighth final match-up between sides from same country
For the eighth time in the Champions League, two teams from the same country will play the final. First, they have a league clash.
Saturday sees the third meeting between Manchester City and Chelsea this season, but crucially not the last.
Both sides advanced through their Champions League semi-finals in dominant fashion this week, setting up an all-Premier League final in Istanbul.
This weekend's game at the Etihad Stadium is a big one for City, who will clinch the title with a win, but it will also be interesting to see how Chelsea approach it.
The Blues were blown away by City under Frank Lampard earlier this season, losing 3-1 at home, yet Thomas Tuchel then masterminded an FA Cup semi-final success against Pep Guardiola's men.
The German will hope to have the upper hand heading into the big European showpiece.
This is far from the first time two teams from the same league have contested the Champions League final, though.
We take a look at the previous seven examples and how the form book looked heading into those matches.
Real Madrid 3-0 Valencia – 2000
The change in the competition's format in the 1990s made these clashes a possibility, and the first such match-up was an all-Spanish affair.
Real Madrid were too strong for Valencia in Paris, scoring through Fernando Morientes, Steve McManaman and Raul, but that game was out of keeping with the rest of the campaign.
Madrid finished fifth in LaLiga, two points behind third-placed Valencia, and took just one point from their two league meetings before saving their best performance for the big stage.
Juventus 0-0 Milan (2-3 pens) – 2003
Milan also lagged behind in the league – perhaps a positive omen for Chelsea – before scraping past Serie A champions Juventus on penalties in Manchester.
The Rossoneri finished third, 11 points off the pace despite each side winning 2-1 in their respective home games against one another.
But Milan brushed aside rivals Inter (second in Serie A) in the semi-finals before getting the better of the Bianconeri from 12 yards.
Manchester United 1-1 Chelsea (6-5 pens) – 2008
Manchester United set the tone early for their Moscow spot-kick success against Chelsea, also beating the Blues on penalties after a 1-1 draw in the 2007-08 Community Shield.
That curtain-raiser kicked off a superb season for United, who recovered from a slow start in the Premier League to beat Chelsea at home in September. They lost at Stamford Bridge in April but still won the title on the final day.
Even then, Alex Ferguson's side relied on "Terry's slippy", as Guardiola put it, to claim a third European crown.
Borussia Dortmund 1-2 Bayern Munich – 2013
These single-country clashes have become increasingly common in the past decade, starting with a treble triumph for Bayern Munich.
They had lost the 2011-12 final on home turf while finishing runners-up to Borussia Dortmund in the Bundesliga, but they righted both wrongs the following year.
Bayern beat Dortmund in both the DFL-Supercup and the last eight of the DFB-Pokal, while a pair of 1-1 draws in the league protected a 25-point advantage at the summit, setting the stage for Arjen Robben to cap the campaign off at Wembley.
Real Madrid 4-1 Atletico Madrid – 2014
Madrid and Atletico matched the Dortmund-Bayern five-match epic 12 months later with a gripping year-long back-and-forth.
Atleti won the league with Los Blancos three points back in third, having crucially lost the home Derbi and then only drawn at the Calderon.
But Madrid proved their worth in knockout ties by winning both legs of a Copa del Rey semi-final and thrashed poor Atleti in extra time in the final game of the season to complete La Decima after Sergio Ramos' 93rd-minute equaliser.
Real Madrid 1-1 Atletico Madrid (5-3 pens) – 2016
It was heartbreak again for Atleti two years later, with these games between familiar foes often so agonisingly close.
Cristiano Ronaldo dispatched the decisive spot-kick in Milan and Atleti did not have a league triumph to fall back on this time.
Neither side could beat Barcelona to the title despite Diego Simeone's men again winning at the Santiago Bernabeu to take four points from their neighbours. Atleti were third, with Madrid second.
Tottenham 0-2 Liverpool – 2019
It is only two years since the last all-English final, although neutrals will hope this year's showpiece is rather more entertaining.
A Moussa Sissoko handball within a matter of seconds took European glory away from Tottenham, who were already underdogs against Liverpool.
Spurs had lost 2-1 home and away against the Reds and trailed them by 26 points in the Premier League, although Jurgen Klopp's men still fell short of City in the title race.
