Antonio Conte's spell at Tottenham Hotspur got off to winning start thanks to a 3-2 victory against Vitesse Arnhem on Thursday.
In front of a raucous crowd in north London, Spurs got their supporters bouncing with an emphatic opening spell.
Son Heung-min latched onto a scramble in the box to make it 1-0 after 14 minutes.
Lucas Moura - starting up front with Kane and Son in a 3-4-3 formation - made it two after breaking free of the Vitesse defence.
With 28 minutes on the clock, it was 3-0 for the home side as Harry Kane and Ben Davies forced an own goal from Jacob Rasmussen.
But it was evident that Conte has his work cut out for him as Vitesse quickly got back in the game.
Rasmussen made up for his earlier indiscretion by getting the Dutch side back into the game four minutes after his own goal.
Five minutes before half-time and Vitesse were down only a goal after Matus Bero took advantage of sloppy play from Moura before slotting past Hugo Lloris.
Cristiano Romero then made Spurs play with 10-men after he was shown a second yellow for fouling Lois Openda.
The personnel advantage was even with 10 minutes left when Danilho Doekhi was shown his second yellow, before Vitesse were reduced to nine-men after Markus Schubert's deliberate handball to stop Emerson Royal's lob.
Spurs are now second in their Europa Conference League group, three points behind leaders Rennes.
Speaking after the game, Conte was relieved to win what he described as a 'crazy' match.
He told BT Sport: "It was a crazy game. Usually I don't like this type of game - a crazy game means anything can happen. But at the same time I think we should win and we won.
"We were winning 3-0 then conceded two goals we can avoid. After a red card we were in trouble. To win while suffering is good for this team, these players.
"They needed to improve their confidence. They needed to work a lot. ThHe problem is we have to find the time to work. We have two days until the next game [they play Everton on Sunday], then it's the international break.
"For sure we have to improve. It's not easy because in two days we prepare for this [Everton] game... now we have only one day. Tomorrow it's impossible to work with the players who played tonight. They used a lot of energy. Tomorrow they have to rest and we'll work with the players who didn't play.
"We need to have a bit of patience because we need to work on many aspects - tactically and physically. I'm not afraid about the work. I know only through the work you can reach important targets."
