Henrikh Mkhitaryan’s agent insists Manchester United fans have not seen the best of the midfielder because he is not fully fit, according to .
The 27-year-old summer signing from Borussia Dortmund was left on the bench by Jose Mourinho for the first three games of the season.
He was handed his first start in the 2-1 derby defeat to Manchester City but was substituted at half-time.
Mkhitaryan picked up a thigh injury while on international duty with Armenia in the build-up to the derby and missed the defeat to Watford on Sunday with the same problem.
But his agent, Mino Raiola, insists he will show why United shelled out more than £25m to sign him when he returns.
He told the Daily Mail: “Mkhi was the best player in the German league the last two seasons. He has a strong mentality and will be an asset once fully fit.”
Raiola also revealed United beat off competition from another Premier League club to sign the former Shakhtar Donetsk man.
Hr added: “We had almost agreed with another Premier League club but Dortmund wouldn’t let him go, then United pushed it over the line.”
