Londoners Chelsea and Arsenal play on Wednesday in Baku, the final of the European football league, with the blues seeking the fifth European title and the Gunners only the second.
In what will be the third all-English European final, the two teams, which in London have their stadiums separated by only 12 kilometers, travel nearly 4,000 to discuss the trophy in the capital of Azerbaijan, with Arsenal having the extra draw of power too securing a place in the next season's Champions League, something that Chelsea have already achieved via the Premier League.
After their triumph in the defunct Cup Winners Cup in 1993/94, Arsenal, who were Sporting's opponents in the group stage (1-0 win at Alvalade and 0-0 in London), are again able to celebrate in a new Continental title and this time has on the bench the Spanish Unai Emery, a coach who well knows what it is to conquer the Europa League.
In the service of Sevilla, Emery won three consecutive times, with Benfica being one of the 'victims' in a finals between 2014 and 2016.
However, the only time Arsenal 'picked up' Chelsea in a European competition was eliminated in 2004 in the quarter-finals of the Champions League (1-2 at Oldbury Highbury and 1-1 at Stamford Bridge).
In fact, the Gunners were always defeated in Europe by teams from the same country, having fallen to Manchester United in the 2009 Champions League semi-finals and Liverpool in the quarters of the same competition in 2008.
For their part, Chelsea, under the command of Italian Maurizio Sarri still has not lost in the race, with a record of 11 wins and three draws, has the chance to re-raise the trophy of the Europa League, something that happened in 2012 / 13, at the time at the expense of Benfica.
The European blues record is wider than Arsenal's, winning the Champions League in 2011/12 and the Cup Winners Cup in 1997/98 and 1970/71.
This season, the two sides met twice, both for the Premier League, with Chelsea winning 3-2 at home on Matchday 2 and Arsenal 'revenge' on the 23rd round, 2-0.
On Wednesday, the two clubs will be on opposite sides, but until then they are 'united' in criticism of UEFA and the place chosen for the final.
At the 70,000-seat Baku Olympic Stadium, UEFA has only made available 6,000 tickets for each finalist, with Arsenal and Chelsea also showing their displeasure at the few air links and the price of hotel units in the city.
The place of the final also led to the departure of Armenian Henrikh Mkhitaryan, Arsenal forward, who self-excluded due to the political tension between Azerbaijan and Armenia.
The meeting that will decide the next winner of the Europa League is scheduled for 20:00 (23:00 local time) and will referee the Italian Gianluca Rocchi.
