Ruben Amorim risks being sacked this weekend because of his stubborn devotion to his football ideals, Alan Shearer has warned.
Manchester United welcome Chelsea to Old Trafford on Saturday and could drop into in the relegation zone if results go against them.
United have made their worst start to a league campaign for 33 years, languishing 14th in the table with four points after four games, but Amorim has insisted he will stick by his 3-4-3 philosophy.
Shearer feels that resulted in a chasm between them and Manchester City in their 3-0 drubbing last weekend - and that Amorim cannot avoid a repeat.
