If you are a bettor, this will be a good chance to bet on Eintracht as they are the underdog here. And if you feel, they have the chance to beat Tottenham, go for it. In this game, everything is possible. Just remember, getting one goal would need hard work from the players. Eintracht has their chance here but need to watch the performance of the players as you will have the idea if they can really overpower the strength of Tottenham guys.
The only reason I will be having expectations for Tottenham to win over Frankfurt is because the English Premier League teams have a special way of play that makes it difficult for team from abroad to compete against them. Tottenham might not be doing so well in the EPL and be winning games in European competitions it has been happening on quite enough occasions so it is possible that Spurs can get a win in this fixture.
Tottenham and Manchester United have no hope of playing in the champions league next season and even ending the season in a European competition lower than the champions league zone is starting to look impossible for them in premier league, so their only hope of course is to win the European league this season, So far they have managed to overcome every pressure in the European league for advance to the quarterfinals and show how they have better abilities in the European league than the English league, just like you, of course I personally believe that tottenham will be able to overcome frankfurt in the two legs of the match later, because if we talk about mentality and quality, tottenham is still far above frankfurt and that should make them more favoured to reach the semifinals.
