Monaco's defensive record in Ligue 1 has been impressive this season, as they have only conceded just seven goals in their first eight matches. This is a far cry from the 48 goals they conceded last season, and it shows that the team is putting in the hard work to defend their title.

In comparison, Manchester United have struggled defensively this season, conceding 22 goals in just six matches. The Red Devils have also had a rocky start to the season, losing four out of their opening five games. However, with the help of new signings such as Bruno Fernandes and Raphael Varane, the team is starting to turn things around and look like a different side than last season.

One thing that both teams share is a focus on defense. Monaco has invested heavily in their defense this summer, signing experienced players such as Benjamin Mendy and Presnel Kimpembe. Meanwhile, Manchester United have signed several young defenders in the hope of developing them into key players for the future.

Despite the strong performances from Monaco and Manchester United, there is still plenty of competition in the top flight. Paris Saint-Germain have already won two league titles this season, and they will be looking to continue their dominance. Meanwhile, Liverpool and Chelsea have also been performing well, with the former winning three consecutive league titles while the latter finishing second last season.

Overall, it seems that the top-flight of English football will be a closely contested battle throughout the season. With so many talented teams vying for glory, fans can expect some exciting matches to come.
