Marc Guehi believes there are no secrets to Swansea City’s extraordinary defensive record this season – just hard work, strength in depth and experience. The Swans kept another clean sheet on Boxing Day as they won 2-0 at Queens Park Rangers to move into second place in the Championship. It was their 12th shutout of the season – more than any other club in all four divisions and their tally of just 12 goals conceded in 21 matches is also the best in the EFL and Premier League, along with Manchester City who have played seven games fewer.
