In addition to their tactical changes, Monaco has also made some personnel changes. They have brought in new players to strengthen their squad and improve their overall performance. These changes have helped to give Monaco a competitive edge over other teams in Ligue 1.

Overall, Monaco's 4-2-3-1 formation and central striker Ben Yedder have been key factors in their successful campaign so far. With continued improvements in tactics and personnel, they are poised to make a strong challenge for the league title.
