Tottenham midfielder Moussa Sissoko admits they froze in defeat to Champions League opponents Ajax.
"The start of the match was not good on our part, we were perhaps intimidated by the challenge," he told RMC Sport.
"We did not play our football. I tried to bring back the impact, in the second half it was better, we could have done better, it's a shame to lose this match but there is a second leg.
"The first thing in football is the impact - especially in this kind of match. This is only the first round."
