Tottenham manager Mauricio Pochettino expects to face a strong Barcelona next month, after stating that no gifts are given in the Champions League.
The direct confrontation ended better for Tottenham, who won 1-0 with Eriksen's goal in the 34th minute.
The news comes as a boost for Tottenham, who need to beat Inter to have any hope of emerging from Group B, where they are now in third place behind Barcelona and the Italian side.
Inter's knowledge that a point would send them through meant they approached their first competitive match at Wembley with extreme caution.
"But I keep on saying that we need to do what we need to do, which is to play and win against PSV".
"I expect they'll play with the best players but I don't know how they'll prepare the game", he told a news conference. Then at the end of our match I will ask what the score of the other match was, but we need to win our game.
"What Barcelona is going to do is not in our hands".
Back in the Champions League after seven years, Inter has the easier task against PSV, which are already guaranteed to finish last in the group and has nothing to play for.More news: ‘No deal or no Brexit’ if Britain’s MPs reject agreement - EU’s Tusk

Pochettino said: "All is possible in football".
"But now we need to focus on Arsenal on Sunday [in] another massive game for us".
Pochettino, who started Eriksen and Son Heung-min on the bench against Inter, hopes his side arrive in good shape for their meeting with Barca on December 11.
'They are serious professionals, ' he said. We have big respect to Barcelona, they are one of the best teams in Europe, it will be a so tough.
"We only need to show again a good level to compete at our best". We need fresh legs, fresh mind and no injuries. "We need to change like basketball so players can go in and out".
A draw and victory against PSV revived Tottenham's prospects, showing the resilience that has Pochettino's side in third place in the Premier League only five points behind Manchester City.
"Every three days playing games is so tough - so tough for us but for our players so, so hard".
Pochettino's relief was clear as he looked to the heavens and pumped his fists, but Tottenham still have one last daunting hurdle to overcome in Barcelona before they can celebrate a last 16 berth.
