"Of course, they have unbelievable players and it'll be so tough, but one thing we have is our belief and faith we can win", he said.
The Dane was the beneficiary of good work by Moussa Sissoko and Dele Alli to score at the far post with 11 minutes left. The ball was quickly laid off to Eriksen who lifted it over goalkeeper Samir Handanovic.
"I think the performance was very good, we fully deserved the victory", said Pochettino.

Mourinho sends a message to his lovers after Champions League progress
Jose Mourinho's tenure at Manchester United continues in its odd fashion as Marouane Fellaini netted late to see his side beat Young Boys in the Champions League .
The Argentinian has forced his way into Pochettino's side in recent weeks, starting the last three Premier League games, but will miss the crunch Champions League clash with Inter Milan on Wednesday as he is not included in the club's 25-man squad. Barcelona are too prestigious to give something away. "I have no doubts about the way they will approach the match". I don't even dare to have a shadow of a doubt. "We are very disappointed with the result, we'll go into the next game and see what happens". But of course in the Champions League, no-one is going to give you a present and not care about the result.
As it stands, Spurs are second in the group, level with Inter on seven points but ahead on head to head record (that's how sides finishing level on points are separated). We have big respect for Barcelona.
"I told you we need English players, but it was impossible".
The Gunners are now on an 18-game unbeaten run under the stewardship of Unai Emery and have already sealed their progress to the next round of the Europa League.
