Christian Eriksen felt Tottenham's poor finishing was to blame for their shock Europa League last-32 exit at the hands of Gent.
A 2-2 draw at Wembley on Thursday consigned Spurs to a 3-2 aggregate defeat and brought their European campaign to an end for this season.
Eriksen opened the scoring after only 10 minutes but Harry Kane scored an own goal and Dele Alli was sent off before half-time, leaving the home side with a mountain to climb at Wembley.
Spurs dominated play after the break but could not complete the turnaround after Victor Wanyama's fine goal on 61 minutes, and Jeremy Perbet's late strike on the break ensured Gent's place in Friday's last-16 draw.
"We are very disappointed with what we did today and over two games against Gent," Eriksen told BT Sport.
"They did not have a shot in the first half but still got a goal. We gave it away after getting in front. We weren't good enough in our finishing or our final pass.
"Overall, we did what we could. The referee was not on our side either. Even with 10 men we had chances to get the winner. We can blame the ref but we had our chances and we weren't good enough."
