Graeme Souness has expressed skepticism regarding Kobbie Mainoo's readiness to be a regular starter for Manchester United, despite the 19-year-old's recent rise in prominence. Following a disappointing performance in a 3-0 loss to Liverpool, where he was responsible for a goal, Souness suggested Mainoo should be used more as a rotational player rather than being relied upon against top teams. While Mainoo has shown potential, including a standout season last year and participation in England's Euro 2024 campaign, Souness believes he is not yet the 'go-to man' for United. The pressure on United's management is increasing as they currently sit in 14th place, having only earned three points from nine available. Additionally, new signing Manuel Ugarte is expected to bolster the midfield but is still working on his fitness. This situation highlights the challenges facing both the young talent and the team amid a tough start to the season.
