Ange Postecoglou expressed frustration after Tottenham came away from Newcastle pointless despite dominating at St James' Park.
'Yeah, obviously we should have got something from the game,' the Australian said. 'It's very similar to our first away game (at Leicester) where we controlled it for the most part. We just needed to kill it off and we didn't.
'The second goal was disappointing. We switched off but it should have been well over by then.
'So it's another sore one unfortunately, where we haven't got the rewards for our play. But it's three strong performances from our first three games. The results don't reflect that.'
Spurs have four points going into the international break but Postecoglou insisted that the rewards would come, with bitter rivals Arsenal next up on September 15.

'The positives are that our football is good and has been in the past three games. We just need to get our rewards,' the Spurs boss added. 'If we continue to play like that, I know we will get them.'
Newcastle manager Eddie Howe stressed that despite his side maintaining their unbeaten start to the season, there is still plenty to improve on.
'It was a tough game, the second half in particular,' he said. 'But it was a great response to find a way to win the game, so those are great signs, but we know that longer term we have to improve our performances.
'We're not playing as we'd like — we don't have enough control and composure — but we are showing our defensive qualities. On the ball, we've got a lot of work to do.'
And Howe admitted his relief that a 'challenging' transfer window was over, with the club failing to strengthen their squad despite being linked with several high-profile players. 'This transfer window has been tough for us,' he said.
'But it gives us stability now that a lot of the off-field stuff will disappear, so we can focus on the pitch and the players that matter and get better as the season goes on.'
