Luke Williams says he's unable to explain how his Swansea City side turned in such a poor performance in the defeat to Hull City on Saturday.

The Swans were punished for a desperately poor performance at the MKM Stadium as Mason Burstow sealed a deserved 2-1 win for the Tigers after Harry Darling had cancelled out Joao Pedro's opener.

The result was Hull's first league success in 14 attempts, and Williams admits his side deserved to leave East Yorkshire empty-handed.

“I thought it was a dreadful performance and a result that matched it for us," he said.

“I couldn’t tell you why we played like this, but we were certainly very, very poor.

“In fairness, I didn’t even celebrate our goal as, from a performance point of view, it was not good enough.

“I was hoping there would be a reaction (from the Sunderland game), but I don’t think we’re in that place as a group just yet."

“They were better than us. We played well against Sunderland for 45 minutes and then we were dreadful.

“I didn’t think either side played particularly well, but I wasn’t expecting that – it was very, very disappointing.”
