Leicester director of rugby Richard Cockerill hailed his side’s resilience as they fought back from 7-31 down to win 38-31 at Gloucester.
Four second-half tries saw the Tigers recover to pick up a last-ditch victory at Kingsholm to stun the Cherry and Whites on the opening day.
Afterwards boss Cockerill was delighted as they kicked off the Premiership campaign with a bonus-point success at a difficult venue to play.
“I’m delighted with the win and the resilience that the players showed. That is something we have been working on in pre-season and we needed every ounce of it tonight,” he told Premiership Rugby following Friday’s win.
“But I was so disappointed with the first 50 minutes because we were pretty woeful and we need to put that right very quickly.
“To be fair we were pretty calm at half-time. We wanted to come out and still play positively because that was the only way to get back in the game, and try and score first to put the pressure back on them.
“Credit to the players, we got our composure back, we scored, and Gloucester ran out of steam.
He added on their comeback: “It was smart play from the team. We got results from the driving lineout and we kept going at it. We messed up a couple of opportunities but it was nice to see a 15-man maul to the line.
“Smart decisions in the last half-hour enabled us to get back in the game and win it.
“We’ve changed our approach conditioning-wise a little bit, we’ve worked hard and pushed the boys a little bit harder.
“It’s a long way to come back from but credit to the players, I’m delighted with the last part of the game but that first 45 minutes is unacceptable from us really.”
