  "We spoke before the game about any team being capable of scoring against you," Southgate said. "We started in a sloppy manner, so that was disappointing.
  "Our response was good, we showed composure to work our way back into the game. The goal difference might end up being important.
  "But if we start games like that against better opposition, it will be a struggle to get back into it."
