Bob Bradley insisted he can turn around Swansea City’s fortunes despite the 5-0 thrashing at Tottenham that sent them back to the bottom of the Premier League.

The defeat led to calls for chairman Huw Jenkins to quit from angry fans with the Swans facing a grim battle for their top flight survival.

Bradley’s side face a critical spell of games where they face five of the bottom 12 teams – Sunderland, Middlesbrough, West Ham, Bournemouth and Crystal Palace – in their next six games.

The run starts at the Liberty Stadium against a Black Cats outfit whose victory over champions Leicester took them off the bottom into 18th place.

Bradley, 58, said: “I’m still confident.

“I think we have made progress, but it’s up to us to prove that. This game speaks for itself, we weren’t good enough.

“But I will absolutely expect us to learn from this.

“We still have some confidence from the last few matches and we must take that into the Sunderland game which is the start of a lot of important matches for us.

“We knew this would be a difficult game for us but the manner in which it went makes us feel frustrated and angry – but we know there’s a lot to play for.”

The Swans were unlucky to fall behind just before the break after Dele Alli appeared to dive in the box with Harry Kane hammering home the penalty.

But Son Heung-min quickly doubled the lead with a superb strike and second-half goals from Kane and two from Christian Eriksen completed another miserable trip to White Hart Lane.

It is now just one win in 14 games for the Swans.

Bradley added: “I didn’t think the referee was in a good position and that penalty decision certainly changed the game.

“Today is a big concern. I think the starting point was Tottenham got to every ball faster. On a day like today it feels like we have a long, long way to go.

“There have been other days where I think there have been promising signs. We have work to do.

“We knew coming here today was going to be particularly difficult. We have to learn from it but go forward quickly.”
