Gylfi Sigurdsson has praised Bob Bradley's start to life as Swansea boss and believes a second league win of the season is not far away.

The Swans appointed the Premier League's first American manager when New Jersey-born Bradley was named as successor to Francesco Guidolin during the international break and Sigurdsson has been impressed.

"The boys really like the new manager," Sigurdsson told Swansea's official website. "Training has been good since he came in -- really hard and really sharp. I think we have improved since he arrived and I think if we keep performing like we did in the next few games, we are going to start picking up a few wins."

Iceland international Sigurdsson admitted disappointment at not being able to take a result away from north London to add to victories at Arsenal on their last two visits.

The 3-2 defeat was their first at the Emirates Stadium since 2011 but Sigurdsson saw plenty of positives.

"We are disappointed not to get something," he said. "We put a lot of pressure on, especially in the last 20 minutes after the red card. It was a very exciting game to watch probably, with five goals and a red card.

"Overall we are a bit disappointed, but then we could have conceded a couple more. There were encouraging signs. It's never easy coming here. Even though we were 2-0 down we kept going, and after 20 minutes we started playing better football. We put a lot of pressure on and had a couple of chances to make it 3-3."
