Swansea City boss Garry Monk admits he's worried after defeat at Norwich City.

Jonny Howson's second-half header left them with only one win since August, meaning that after a promising start to the season they will join the battle against relegation unless they swiftly improve.

"Of course I'm concerned," the Swansea manager said. "We're here to win games and get points. In my time as manager we've done that very well. These difficult periods are part of it and part of management. I understand what needs to be done, but of course it's a concern.

"It's not the lowest (I've felt). It's not a good moment for myself, but I'm a fighter. I've been at the core of that (at Swansea as a club) for a long, long time and I understand that.

"We had total control up until their goal, albeit we weren't sharp enough in that final third up to that point, which is disappointing, but we had total control.

"We get caught with a lack of concentration which is costing us dearly at the moment, dearly. We end up losing the game from that one lapse of concentration, which is frustrating.

"Any set-piece is a soft goal, bitterly disappointed. Ultimately it's cost us the game.

"No (we don't lack a Plan B), we just didn't do enough with the ball in the final third. To come here and have total domination of them was part of our plan and we executed that well.

"The key to it all is (the players are) good enough. It's that little bit of extra that's needed right now and it's for me to drag that out of the players and for themselves to focus on that as well."
