The Whites have shipped 50 top flight goals in 33 Premier League outings so far this season, the most by any team currently in the top ten.
However, Leeds are currently on a six-game unbeaten streak in the league and have not conceded more than one goal in a game in that period, despite facing the likes of Manchester City, Chelsea, Liverpool and Manchester United, while also earning two clean sheets.
Leeds shot-stopper Meslier has insisted the team vastly improved their defensive game in the second part of the season, which he stressed is evident from them being more solid at the back.
Meslier added that improving defence has also had an impact on the Whites’ performances at the other end of the pitch, as a strong backline provides a bedrock for the attacking department to push on.
Asked how much have Leeds progressed in the Premier League, Meslier told LUTV: “Yes, but we have conceded less goals since the first part of the season.
“So, I think it is in defence where we have progressed the most, [made] the best progression.
“I think after we run less for nothing, I don’t know if you understand.
“For me it is clear we defend better and so we attack in better condition [as well] to try to score.
“But I think the [better improved area] is the defence.”
Leeds will be keen on extending their unbeaten streak to seven with a win at the weekend when they take on Brighton & Hove Albion at the Amex in the top flight.
