Alexis Sanchez has been pictured arriving at Manchester United's training ground to complete his transfer from Arsenal.
The 29-year-old forward is widely expected to complete his move to the Red Devils on Monday, with Henrikh Mkhitaryan heading in the opposite direction.
Sanchez arrived at Carrington after lunchtime on Sunday to undergo a medical. Earlier, the Chilean posted video on Instagram of him boarding a private jet.
Sanchez is to become United's best-paid player, with Telegraph Sport exclusively revealing last week the deal will cost Manchester United £180million over the four-and-a-half-year deal.
Steve McClaren, BBC Radio 5 Live's Sportsweek programme, warned that Sanchez's salary could create dressing-room disharmony at United.
"That is the danger in the modern game and the problem I find in clubs," said McClaren, the former England manager and Sir Alex Ferguson's assistant when United won then treble in 1999.
"Wage parity is very important to players. Yes, they find out - at all levels - and if someone is paid a lot higher than others that can cause a problem.

"In the short term I don't see a problem, but in the long term for Manchester United they will have to solve that problem.
"If he (Sanchez) is on the wages that is being bandied about then other players will know that when their contracts come up or they are in demand from other clubs.
"The others will be looking at renegotiation next season or the season after and getting to that (wage) level if they think they are at that level."
