Spurs made it three wins on the bounce with a 1-0 triumph over the Eagles.
“Honestly I think we deserved to win because we played aggressively and we created some big chances,” he told the official Spurs website.
“Palace were good and they created chances as well but our defenders did good work.”
The Argentine was one of the standouts in a strong team performance that saw Spurs edge a narrow 1-0 win on Sunday, and he will hope to build on his recent form.
The 23-year old shone coming off the bench against Sunderland the previous Sunday - setting up the winning goal - and followed that up with a goal of his own midweek against Qarabag in the Europa League. He capped the week off with a fine display against Palace and is showing signs of becoming a more effective player for Tottenham.
His quality is apparent, but consistency and decision making has always been the issue and Spurs fans will hope his last few performances signal a change in his game.
Lamela’s praise for the Spurs defence is warranted, given that Sunday was their third consecutive clean sheet in the Premier League, and it suggests Mauricio Pochettino is finally starting to get things right at the back after 16 months in charge.
