Tottenham boss Mauricio Pochettino questioned his players' desire after their 2-1 defeat at Crystal Palace.

Spurs took the lead through Harry Kane before goals to Dwight Gayle and Jason Puncheon earned the hosts the three points.

Pochettino was coy when asked about the referee's display, with his side's inability to break into the top four his main annoyance.

"I don't want to speak about the referee," he said. "I think it is a very difficult job, but it is true the penalty decision changed the atmosphere.

"Maybe after we suffered a little bit, Crystal Palace believed they can come to get the three points.

"A lot of long balls came in and I think that in this challenge they wanted it more than us.

"We are disappointed with the result and we lost a good opportunity to stay with the top four."
