Philippe Clement thanked the Rangers supporters for backing their team in the 5-0 win over Dundee at Dens Park but asked them to leave the pyrotechnics at home in future.
The match was delayed by 45 minutes after the Rangers team bus was held up in traffic and then suspended for 18 minutes after the travelling fans let off a large number of flares that triggered fire alarms under the stand.
Rangers were unaffected by either delay as they ran out comfortable winners thanks to goals from Ryan Jack, Danilo, Sam Lammers, Cyriel Dessers and James Tavernier.
Clement was pleased with his players’ focus but hoped there would not be future firework displays from the Rangers fanbase.
The Belgian said: “I expect a team that’s always ready no matter what happens, even if they say we have to play in the car park.
“We need to be ready because we play this game to win, so we must always be ready to adapt to the situations.
“The players were ready and after going inside again it was the same. Because you have five minutes in the dressing room it doesn’t mean you lose your focus.
“They need to be winners so whatever circumstances, whatever pitch, whatever weather, we are there to win games. That’s the mentality I want.
“I hope that the club does not face sanctions. You come here in the warm-up and the stand is full, everyone is chanting and supporting the players, giving a lot of energy.
“Those are very important things. We feel also the dynamic between fans and players is changing and it’s because of both sides.
“It was good the team started bright again, but I think everyone will understand that it’s really good to have all this support, all these songs and all this energy – I love it – but keep the fire outside of the stadium.”
Dundee boss Tony Docherty admitted he thought the game was going to be abandoned when referee Kevin Clancy took the players off the pitch.
He said: “It was a bizarre night and at one stage I thought the game wasn’t going to go ahead. I was trying to keep the boys focused.
“Then we start the game and because of the pyros we get brought in again. There’s a debate on whether there’s a place for that but the game was almost abandoned.
“The police took control and I didn’t think we were going to go back out again. That affects focus. When it’s almost causing matches to be abandoned I think we need to address it.”
