The Three Lions had taken an early lead in Prague thanks to Harry Kane's penalty but the Czech Republic were level before the ten minute mark.
I think we were better in the second half and we created chances to win the game.
"I always have to accept responsibility", Southgate said.
"From when the manager came in he told us the style of play, how he wanted us to play, how to press".
Southgate, who suggested his players will respect the UEFA's three-step protocol if there are racial flashpoints in the games against Czech Republic and Bulgaria, moved to placate tensions, saying: 'I can totally understand why the Bulgarian president feels as he does because we have purely been responding honestly to questions we've been asked.
"And in terms of a wake-up call, I think we've had a lot of plaudits".
"We probably should've got a draw out of it, but in the end the goal we conceded was typical of the chances we gave up throughout the night".
"I think it's unfortunate because you can foresee the risk". We have a couple of days to regroup, not long, and we have to reward our supporters with a better performance than we gave tonight. "Throughout the night, we were too open". He switched to 4-3-3 after the interval, when England did look more cohesive.
"We started the second half a lot better and had chances, but we conceded too many poor chances and gave the ball away too many times".
"That said, at 1-1, at half-time, we were able to change that".
"Collectively we have to accept there were not enough good performances".
"It was a 100 per cent performance and that is the only way to succeed really, so we are very happy and I think time will show that we made history tonight because we defeated England after so many years and at a time when they are playing really well. We knew we'd have to be at full tilt to deal with the Czech Republic but we should have been strong enough to deal with them". They had the crowd behind them, sometimes the pitch is not as easy to play, but that's no excuse.
