Rio Ferdinand has urged Ruben Amorim to make Man United's stars 'uncomfortable' and stick with his tactical approach despite their struggling form.
A miserable 2-0 Monday night defeat at home by Newcastle leaves the Red Devils 14th in the Premier League and just seven points above 18th-placed Ipswich Town.
To make matters worse, questions are already being asked over Amorim's tactical approach - with the side now having suffered four consecutive defeats.
However, former United defender Ferdinand has insisted that the former Sporting Lisbon boss should stick with his guns to get them out of their current rut.
