Gary Neville has cast doubts on whether Ruben Amorim's preferred back three formation will suit Manchester United, suggesting the new boss might have been better off taking over next summer. Despite the excitement surrounding Amorim's appointment after a rocky tenure under Erik ten Hag, which saw two domestic cups victories but league performances scrutinised, Neville is cautious about the expected tactical shift. Yet, Neville harbours concerns regarding Amorim's favoured defensive strategy, a concern seemingly shared by Liverpool and Manchester City, yet maybe missed by fans excited by Amorim's arrival.Both clubs reportedly passed on Amorim due to his back three system not aligning with their squads. While Neville is optimistic about Amorim's potential impact, he questions how United's current defenders will adapt to the new demands, especially after years of playing a back four under Ten Hag.
