It's a very nice observation and it's a very nice achievement ending almost two decades of trophyless seasons, but the thing, for as long as I can remember this is the first time I'm seeing Tottenham ending in such a position in the league since I started following football almost 20 years and these years I only saw Tottenham lift the league cup which isn't up to the standards of the Europa league. In all these years that Tottenham were an average team, they won nothing in all of these 16 years that they ended up in a better position in the league. This time around they were poor in the league but strong in the competition. Sometimes success do come from what we perceive as failure.
Everyone has their own reasons and Tottenham are indeed no longer focused on the Premier League and they have defeated all their focus and energy for the Europa League competition, it happened over time when they saw the possibilities for them to achieve and it was quite successful for Tottenham, the Europa League Trophy is very prestigious and they won it of course because it will make the mentality and spirit of this team much more developed in the next season after the long wait has finally been achieved.
