Manchester United are signing Alexis Sanchez from Arsenal in a cashless deal.
The Daily Mail says Alexis is joining United in a straight swap for Henrikh Mkhitaryan.
Mkhitaryan has agreed personal terms to move to Arsenal in the opposite direction.
The final breakthrough came on Saturday morning when terms of the swap deal with Mkhitaryan were finalised. Sanchez was immediately able to make plans to travel to Manchester where he was set to meet United's medical staff, who had earlier been at Turf Moor with the team.
Mkhitaryan was pictured in London on Saturday evening along with his agent Mino Raiola. Marcos Rojo, who travelled down to the capital with his family for a weekend break, bumped into Mkhitaryan at a hotel and the duo embraced.
Both formal announcements may wait until Monday because work permits are unlikely to be sanctioned over the weekend.
