(CNN)Arsenal will face Chelsea in another all-English final after both London clubs made it through to the Europa League final on Thursday.
Arsenal to face Chelsea in all-English Europa League final
A day after Tottenham set up an all-English Champions League final against Liverpool, Arsenal overcame Valencia in Spain, while Chelsea held its nerve to defeat Eintracht Frankfurt 4-3 on penalties.
It is the first time one country has provided all four finalists for both the Champions League and Europa League.
While Arsenal's route to the final was rather more sedate, Chelsea's was anything but after it was taken all the way to penalties by an exciting and adventurous Eintracht Frankfurt.
With the tie level at 1-1 after the first leg, it was Chelsea that struck first at Stamford Bridge through Ruben Loftus-Cheek after 28 minutes.
The visiting side hit back four minutes after the interval through Luka Jovic, one of the most sought after strikers in Europe, with the forward racing through to slot the ball past the stranded Kepa Arrizabalaga in the Chelsea goal.
Both teams had chances to win the tie in the additional 30 minutes of extra time but David Luiz's spectacular block on the line denied Sebastien Haller, while Chelsea captain Cesar Azpilicueta's effort was ruled out for a foul on the Eintracht Frankfurt goalkeeper.
With the scores level at 1-1 on the night and 2-2 on aggregate, it was left to penalties to separate the side with Kepa the hero for Chelsea.
The Spaniard saved two spot kicks, allowing Eden Hazard to fire home the winner and send Chelsea into the final.
For Kepa, who was caught up in controversy after refusing to be substituted during Chelsea's shootout defeat by Manchester City in the League Cup final earlier this year, it was a moment of redemption.
"Penalties are down to luck. Today we won and in the Carabao Cup final we lost, but this is football," Kepa told BT Sport.
"Today was really good and we played against a very difficult team and we are very happy.
"Our season was a little bit difficult but we have reached two finals and we have qualified for the Champions League so I think it's a good season. Now we will have a strong London derby with Arsenal in Baku."
