A plane carrying a banner calling for Ed Woodward to leave Manchester United has been flown over Turf Moor ahead of their Premier League clash with Burnley.
The banner, bearing the message Ed Woodward A Specialist In Failure was seen flying over the stadium in the hour before kick-off on Sunday.
It is a reference to Jose Mourinho s description of former Arsenal boss Arsene Wenger as a specialist in failure while he was at Chelsea back in 2014.
The flyover was reportedly due to take place ahead of Monday s 3-0 defeat to Tottenham at Old Trafford but was postponed due to light restrictions.
It is the first such protest by Red Devils fans since a plane carrying a Wrong One Moyes Out message flew over Old Trafford in March 2014, calling for the sacking of then-manager David Moyes.
The United faithful have become increasingly angry towards executive vice-chairman Woodward and the club s owners, the Glazer family, in recent months.
Supporters have largely taken the side of under-fire manager Mourinho in the wake of a disappointing transfer window, in which Fred, Diogo Dalot and Lee Grant were the only signings.
Mourinho is said to have been incensed by Woodward s refusal to sanction bids for new centre-backs including Harry Maguire and Toby Alderweireld.
United have spent close to £400million since Mourinho s arrival in May 2016, but there is a sense he was undermined during the transfer window by Woodward s reluctance to release funds, especially since the manager was given a new contract only in January.
Mourinho is under intense pressure to improve results on the pitch following back-to-back losses to Spurs and Brighton and Hove Albion, but some United fans stayed to applaud him on Monday and the visiting contingent were heard chanting Mourinho s red and white army after the plane flew by on Sunday.
Most reports in the UK media have suggested Woodward is in no rush to dismiss a third United manager in his time at the club, despite suggestions of a breakdown in their relationship.
