The Manchester United squad were shown a re-run of December's derby loss to rivals Manchester City on Friday.
The Red Devils travel across town to the Etihad later today knowing another defeat to Pep Guardiola's team will secure the Premier League title for the Citizens, with six games left to spare.
United boss Jose Mourinho, however, is clearly in the mood to delay the inevitable party after forcing his players to review the 2-1 Old Trafford loss to City, which saw him accused of 'parking the bus' and his team managing just 35 per cent possession, much to the anger of their own supporters.
Insiders at United's Carrington training HQ have revealed Mourinho has spent the last few days reminding his players of the ugly spat which also followed that reverse.
Mourinho was allegedly splashed by milk after marching into the visitors' dressing room at the final whistle and demanding the City players show more 'respect' by toning down their noisy celebrations.
The Portuguese tactician has still to get the better of his old foe Guardiola in the Premier League since the pair renewed their hostilities in Manchester, losing twice and drawing another.
City could make a number of changes with one eye towards Tuesday's Champions League quarter-final second-leg tie at home to Liverpool, facing the uphill task of trying to turn around a 3-0 deficit, but Jose has ensured his own men are still primed, regardless.
