Henrikh Mkhitaryan arrived at Manchester United's Carrington training ground on Friday as he remains on the brink of a move to Arsenal.
The Armenian midfielder is ready to move to the Emirates in the deal that will see Alexis Sanchez move in the opposite direction to Old Trafford.
Mkhitaryan trained with team-mates on Thursday as the Reds prepare to face Burnley at Turf Moor on Saturday but Friday may prove to be his last visit to the training ground.
United's ongoing pursuit of Sanchez is likely to be resolved on Friday with the Chile's arrival rendering Mkhitaryan surplus to requirements under Mourinho.
