Leeds United drew with Brentford back in October.
Following the 1-1 draw between Leeds and October, Jansson did a post-match interview with Sky Sports and swore on live television.
The Sweden international central defender was clearly angry and frustrated at the final result and with the referee.
The 27-year-old defender - joined Leeds on a season-long loan deal from Torino in the summer of 2016 and made the move permanent in the summer of 2017 for a fee reported by The Yorkshire Evening Post to be worth £3.5 million - has given his take on the situation.
Jansson told Sky Sports: "It is quite new for me to do an interview directly after the game, because I never did that in Sweden or Italy. You are so pumped up at that point, and after that game I had scored a late goal, there were a few situations with the referee and I thought we deserved to win.
"I am not the best to speak after a game because of how I am as a person. If I was more calm it would have been better, and I know you shouldn't talk badly or swear on TV, but if you want to be close to the players then that will happen. I think people who were watching will accept and understand that.
“When you are older and more experienced you have to realise you can't say everything you think. But I am an honest person, when I am bad I want to hear it from people and I will also tell people when I expect more from them. Next time I'll think about what I say, but I will still be honest."
Jansson is one of the best defenders in the Championship and is playing well for Leeds at the moment.
Marcelo Bielsa’s side are at the top of the league table at the moment with 51 points from 26 matches, just two points clear of second-placed Norwich City.
