Former Manchester United assistant coach Chris Armas admits last season's Champions League exit was the moment belief in Ralf Rangnick's and his squad began to wane.
Rangnick was appointed interim manager late last year in a bid to steady the Red Devils ship following a run of dismal form under Ole Gunnar Solskjaer. Former United States international Armas soon followed the German to Old Trafford and served on his coaching staff before both men left the club in May, following Erik ten Hag's appointment.
Rangnick's arrival did bring about marginal improvement but United continued to be plagued by inconsistency as they stumbled to a sixth-place finish in the Premier League. Armas suspects things began to go downhill when the Red Devils were beaten 1-0 at home by Atletico Madrid to exit the Champions League at the last-16 stage, having drawn the first leg 1-1 at the Wanda Metropolitano.
