Ki Sung-Yueng admits Swansea City players have no idea why they can't buy a win.

They have lost their last three league games without scoring after winning their first three and Ki says they are scratching their heads over what's wrong.

"If you lose, a lot of opinion is coming," said the South Korean midfielder. "I think we are just a little bit confused because we won the first games and now we've started to lose them.

"It's important we don't get used to losing. We have to get back to winning again."
