Sean Dyche felt his side were finally worn down by quality as Spurs closed the gap on leaders Chelsea with a hard-fought victory At Turf Moor.
Second half goals from Eric Dier and Son Heung-min saw the Londoners home after the Clarets had more than match the visitors for an hour.
The Clarets boss said: “I was pleased with the team we picked and the way they delivered a performance until the (first) goal.
“I thought for the first half it was a good performance and at the start of the second half we still looked strong and in it, but then we gave a really poor goal away and it changed the whole feeling.
“It’s interesting to see, even at their level, the power of strength they have as a club because the goal seemed to give them more belief.
“We know they are second in the Premier League for a reason, but they kept the ball better after the goal and we couldn’t find our feet for the next 20 minutes, which really changed the rest of the game.
“On reflection, they as real top side and it’s a big learning curve for us again about the details in a game.”
Dyche added: “It’s a strange position to be in, on days like today, because you have to balance out the strides we have made against the team you are playing.
“With the injuries they had – and we wish Harry Winks well - they actually brought players on who you could argue were stronger than those starting the game.”
The defeat, coupled with wins for Hull City and Crystal Palace, left the Clarets five points above the relegation zone with eight games remaining.
And Dyche insisted: “We don’t think we are on easy street for one minute.
“Everyone keeps saying how many points we might need, but I haven’t said anything because I know how difficult this division is.
“We’ve just come off a really tough run of five away games in seven and the two home games have been the top two, Chelsea and Tottenham.
“But there are no ‘gimmes’ and the work continues. We are still in good shape and we’ve earned that right. Now it’s about good focus and concentration on the challenge in front of us.”
