Mkhitaryan, 27, will be the first Armenian player to play in the English Premier League, widely credited with being the most competitive football league in the world, and only the second player from the South Caucasus. Georgi Kinkladze, a Georgian midfielder whose dribbling skills left opposition players flat-footed, played for Manchester City in the Premier League in the 1995/6 season.

Unveiling Mkhitaryan at Manchester United’s Old Trafford ground, manager Jose Mourinho said that his new attacking midfielder will make an immediate impact.

“Henrikh is a real team player with great skill, vision and also has a good eye for goal,” he said.

Mourinho, who took over as the Manchester United manager in the summer, has been given the task of rebuilding the team after they finished fifth last season, missing out on a place in the UEFA Champions League, Europe’s top club football competition.

Mkhitaryan, who had played in Germany for Borussia Dortmund, said it was a dream come true.

“I am excited to play for a club with such an illustrious history and hope to be part of it for a long time,” he said.

Mkhitaryan was born in Yerevan in 1989. His father was Hamlet Mkhi taryan, one of the most prolific Armenian strikers in the 1980s. Mkhitaryan is now considered one of the best Armenian players and has won international 59 caps, the first when he was 17-years-old, and scored 19 goals.
