Redknapp was pleased with the energy of his side which contained youngsters such as Jake Livermore, Thomas Carroll and Kyle Walker, but he maintained that the Premier League would remain his priority this season.
Redknapp said: "We'll give it (the Europa League) our best shot and see where it takes us. Hopefully we can get through the qualifying group and then look at it again.
"The Premier League is always, for me, the biggest. It's no good at the end of the year people saying Tottenham did well, they got to the semi-final of the Europa League, but finished seventh or eighth in the league again. That's not what I want.
"I want us to have a real go in the Premier League this year and we are capable of doing that. We have fantastic players here, we play some great football, we are a good team."
