There are plenty of similarities between these two, but not in the way they'd like as they're both woefully out of form in their domestic leagues and both are now facing a tough battle to make the Champions League by making the top four.
Valencia have lost three of the last five while the Gunners have lost three in a row as they've both lost ground in the top four race, meaning the Europa League may offer the best route back into Europe's elite competition next season.
Unai Emery beat Valencia as Sevilla boss in the Europa League semis five years ago and he's the master at this competition - as he showed in the last round when Arsenal were very impressive in disposing of Napoli, but their form in the league since has been a huge worry.
It's not unusual for Emery teams to fade towards the end of the season when they're chasing Europa League glory, and that may well be the case again as Arsenal have been incredible at home in this competition and haven't even conceded on home turf in this campaign.
As a former Valencia boss, Emery knows all about the opposition, who will miss former Gunner Francis Coquelin through suspension and probably Denis Cheryshev and Geoffrey Kondogbia through injury - all of which makes it a huge uphill battle for the Spaniards who you suspect will be happy enough to just grab an away goal.
Prediction: Arsenal 2-1 Valencia (Sky Bet odds: 15/2)
Best Bet: Arsenal to win at Evens
This is by far Chelsea's toughest Europa League test so far against a German side that managed to overturn a 4-2 first leg deficit to dump Benfica out in the quarter-finals and in Luka Jovic have one of the hottest young strikers in Europe.
These two teams are the top two scorers in the Europa League, while Olivier Giroud is the tournament's top scorer, so there should be a few goals going in - and while Chelsea's domestic away form has been patchy at best, in this competition they've been coasting through the rounds having won every game in the knockout stages.
With a boisterous home crowd behind Eintracht this will be more like a top-level Premier League away game for Chelsea, and they've struggled immensely in those so far this season, so despite fancying them to get through to the final I'm reluctant to push the button on them winning this first leg.
With Eintracht sticking four past Lazio, Marseille and Shakhtar, they're not afraid of piling up the goals and Chelsea will have to weather something of a storm, especially early on, but with Hazard expected to play and Giroud red-hot in this competition, Chelsea should at least get an away goal that will help them for the second leg.
Prediction: Eintracht Frankfurt 2-1 Chelsea (Sky Bet odds: 9/1)
