Shaun Wane was left a 'bit annoyed' with the attitude of his players, despite watching his Wigan side come through 36-14 against London Broncos.
The Warriors trailed 10-0 inside the opening 10 minutes as they conceded two quick tries for the second successive home game.
But the Super League champions and Challenge Cup holders got in to the game and ran out worthy winners at the DW Stadium with Dan Sarginson, Tony Clubb and Iain Thornley grabbing two tries apiece and Matty Bowen scoring a wonderful solo effort.
Wane said: "I was never nervous, a bit annoyed maybe, and I was upset wanting half-time to come so I could say my bit, but I wasn't nervous.
"I thought we would always get the win but they put in a very spirited performance and ran hard. I have watched all their games this season and that is the best they have played this year.
"We need to get used to the fact that people are going to come here and they will raise their game because they are playing against the double winners. That is what London did and I don't think we were ready for it.
"I thought we were worthy winners but there were parts of the first half I was really disappointed with.
"I know what it's like as a player in those type of games and you need to show respect because Super League is a very competitive league and if you don't turn up with the right attitude you will get burned. We tested ourselves today put it that way."
Broncos' coach Tony Rea admitted he was immensely proud of his players and his believes there is still good things to come this season.
The Broncos headed into the game without a single win this season and for the best part of an hour they pushed the reigning champions all the way.
Rea said: "We were outrageously gutsy and sensational. I thought we were wonderful and really took the game to them at the start.
"We came up here and really went at the contest. If there is a negative we made too many errors in our own end and we just needed to stay tidy in the middle block.
"We have been building and every game is important to us. I do expect good things for the rest of the season."
