"When a player of that ability comes along, I think you got to be in the market for him", Irwin, who played over 500 games for United during 12 trophy-laden seasons, told Reuters.

"The Enviable Gold of Alexis" headlined La Tercera, trumpeting that the 29-year-old "has become the best paid Chilean player in history, with the highest salary in the Premier League and the fourth highest in the world". Arsenal's aim all along was to solidify a replacement pre-sale, and BBC have reported that Henrikh Mkhitaryan has agreed personal terms.
