Swansea City goalscorers Alfie Mawson and Martin Olsson believe hard work on the training field is behind their surge away from the Premier League relegation zone.

The Swans’ 2-0 victory at home to Leicester City on Sunday has lifted them four points clear of the bottom three.

When Paul Clement arrived as manager the club were four points adrift of safety, but four victories in six games have transformed the outlook.

Olsson, who scored his first goal since his £5m move from Norwich City, said: “There’s no secret. We just work very hard on the training field and it’s very intense.

“The players are together and make it a good atmosphere and I’m really enjoying my time at the club.”

Mawson, who struck the opening goal with a superb volley for the centre-back’s third goal of the season, revealed: “The manager works us very hard and has a saying – hard week, easier weekend.

“The manager has come in and changed a few things. All the players have never worked so hard.

“We showed that towards the end of the game because we still felt fit and against a team like Leicester, you have to be fit.”

The success of the quiet revolution undertaken by Clement can be gauged by looking at the form of his team in the last six games, compared to the rest of the table.

Only Everton have taken more points over the same period – 14 compared to Swansea’s 12, which is the same total as resurgent Manchester United.

Even Chelsea – the Swans’ next opponents on February 25 – have only managed to take 11.

“We’re in good form at the moment,” said Clement. “Even against Man City we played well in the second half and could have got more. To back up the Southampton game with another home win is very pleasing.

“We’ve worked hard with them on the training ground to get the basics right, nothing complicated. It has brought confidence on the pitch. Then its down to them to execute and they’re doing that really well at the moment.”

Despite the good run that has taken them away from the relegation zone, Clement insists there’s still a long way to go until they are out of trouble.

“There’s a massive amount to do,” he said. “What we’ve been doing is taking every game as it comes, working at what we need to work on and looking at the opposition where we can exploit them. That’s what we’ve got to do for the next game against Chelsea. Nothing more.”

Clement also praised Mawson for the composure he showed in scoring Swansea’s opener, a well-taken volley after 36 minutes.

“It was a lovely finish at the end but the header back across from (Federico) Fernandez to pick him out was excellent,” he said. “There was still a bit to do but it was a very well taken goal.”

Of his goal, Olsson added: “It was great link-up play with Gylfi. His pass was superb, and as soon as I went in on goal I thought to myself ‘just smash it’.

“I hit it as hard as I could and I needed to at least hit the target. I got a great connection and the power just managed to beat the keeper.  Kristoffer Nordfeldt told me before the game that he had a feeling that I’d score. Hopefully he’ll say that in the next game too!”
