Haaland failed to score in Dortmund’s 2-1 defeat at the hands of Manchester City in the first leg of their Champions League quarter-final tie on Tuesday night.
The Norwegian goal machine’s future at Dortmund has been under the scanner and his entourage have been meeting the representatives of some of the biggest clubs in Europe over the last week.
Chelsea and Manchester City are interested in him and he is also believed to be a top target for Manchester United.
But Terzic stressed that there have been no conversations with Haaland over his future and feels he is happy with life at Dortmund.
The Dortmund coach told Norwegian broadcaster TV2: “There has been a lot of talk about Erling in the outside, but our talk with him has been good.
“He is happy with us. What happens off the pitch does not affect us, we cannot prevent people from travelling across the world.
“We are really happy that Erling is with us.”
Dortmund are seven points off the top four spots in the Bundesliga and there are suggestions that Haaland will leave if they do not qualify for the Champions League.
Terzic insisted that everyone at Dortmund wants to play in the Champions League as well.
“Borussia Dortmund always want to play in the Champions League.”
Haaland’s entourage met Barcelona and Real Madrid during their visit to Spain last week.
