Jose Mourinho on Alexis Sanchez Henrikh Mkhitaryan swap deal

Manchester United on Monday confirmed the signing of Alexis Sanchez from Arsenal, with Henrikh Mkhitaryan heading in the opposite direction.

Sanchez is expected to be the highest ever paid player in the Premier League, with British media reporting a pre-tax salary of £500,000 ($695,000, 567,000 euros) a week.

The swap deal that sees Armenia international winger Mkhitaryan, also 29, head to the Emirates following a mixed 18 months at Old Trafford had been expected for several days.

Sanchez had joined Arsenal in 2014 for £31.7 million after three years at Barcelona.

"Alexis is one of the best attacking players in the world and he will complete our very young and talented group of attacking players," said United manager Jose Mourinho.

"He will bring his ambition, drive and personality, qualities that make a Manchester United player and a player that makes the team stronger and the supporters proud of their club dimension and prestige.

"I would like to wish Henrikh all the success and happiness that I am sure he is going to get. He is a player that we will not forget, especially for his contribution to our Europa League victory."

Mkhitaryan joined United for around £30 million in 2016 after three years at Borussia Dortmund.
