And the Portuguese acknowledged that, if Spurs wish to take three points from their first fixture at White Hart Lane against West Brom on Saturday, they must improve their ability to close out games.
"First of all the concentration, the communication between the players and the consistency we showed defensively during the 90 minutes, where we stayed organised," he told the club's official wesbite.
"You find it hard to think about Newcastle’s opportunities and you remember our opportunities when we hit the post and the bar.
"It was a pity we didn’t hold on to the momentum of 1-1 for a longer time, because the boys deserved to get something out of this game.
"The team has to continue trying to do this for the next games and if that happens, it’s important for us to then take three points at home."
