Tottenham Hotspur manager Andre Villas-Boas asked for a Tromso fan who was shouting abuse to be moved to another seat during the clubs' Europa League tie.
Norwegian newspaper Nordlys reported that supporter Reidar Stenersen Jr had been shouting "sacked in the morning" at the under-pressure Spurs boss during the first half. And when he did the same again when the referee blew the whistle on a goalless first half, Villas-Boas asked for something to be done about it.
Villas-Boas is fighting for his job after a 6-0 thrashing at Manchester City on Sunday, the third successive Premier League game in which Spurs have failed to score. They did go on to win 2-0 in Norway on Thursday.
"I first sung after five minutes that he would be 'sacked in the morning' and he looked at me," Stenersen told the paper. "At the half-time whistle, when it was still 0-0 and I started the same song, he pointed at me and suddenly the security came and threw me out.
"I know he is under a lot of pressure so I think my words hit him, even though I am only a little guy in little Tromso. He was being a bit petulant. This is the same thing that can be sung by 60,000 at the Emirates Stadium or other grounds."
Tromso's head of security, Hans-Thore Hanssen, confirmed that Villas-Boas had complained to a UEFA inspector, who then asked for action to be taken.
"He was asked to move to the other side," Hanssen said. "I was not there when the incident happened so what he may have shouted, I cannot say.
"But I know that he [Villas-Boas] had spoken to the UEFA inspector who, in turn, spoke to our security. The situation was handled correctly. If there is verbal abuse shouted, the supporter should be spoken to and, in some cases, thrown out. In this type of match, there is greater security."
