Manchester United defender Luke Shaw is reportedly unhappy at being publicly slated by Jose Mourinho. The 21-year-old fullback was blamed by Mourinho for United conceding one of their goals in their 3-1 defeat to Watford on Sunday (18 September) – but Shaw is said to be disappointed by his boss' decision to criticise him in public.

Shaw reportedly feels Mourninho should have offered him more private feedback on his mistakes against Watford, rather than voicing them to the press, according to The Times. The outspoken Portuguese coach questioned Shaw's "tactical and mental" attitude following three successive defeats for the Reds.

The duo reportedly exchanged strong words when Shaw returned to the bench after being substituted, with Mourinho later saying he should have pressed Nordin Amrabat before Watford took the lead in the 84th minute at Vicarage Road.

Subsequently, however, it has emerged that Shaw was suffering with a groin injury in the second half, which has since been diagnosed as a minor tear. Shaw is set to miss United's EFL Cup tie at Northampton Town and is considered to be 50-50 for the Premier League visit of Leicester City on Saturday (24 September), according to the BBC.

If that is the case, the likes of Daley Blind, Marcos Rojo and Matteo Darmian could all replace him in the United side.
