Stoke City goalkeeper Thomas Sorensen feels they must get back to basics after recent poor results.

Sorensen was pleased to make his first Premier League appearance of the season against QPR, but has warned the Potters about the dangers of becoming complacent.

"It was frustrating to come back in and not really be able to affect the game," Sorensen told Sky Sports News.

"We conceded three goals and I couldn't do anything about it.

"I was happy to have played, but frustrated to have conceded three goals.

"You always have to stick to what you're good at and do things properly and not start to get a bit complacent.

"We had a good start to the season, but now we are in a sticky patch. It's basic defending that we need to do right, like know where your man is in the penalty area."
