The Armenia international completed a move to Arsenal from Manchester United in the January transfer window after Alexis Sanchez sealed a switch to Old Trafford as part of the swap deal.
Mkhitaryan was handed the number seven shirt after he signed a long-term contract with the Gunners in a bid to kick-start his Premier League career following a difficult spell at Manchester United.
The 28-year-old struggled to replicate his Borussia Dortmund form on a consistent basis at Old Trafford despite the attacking midfielder scoring some spectacular goals during his 18-month spell as a Manchester United player.
Jose Mourinho was regularly critical of the Armenian in the media despite Mkhitaryan contributing to their Europa League and League Cup triumphs in his first season at Old Trafford.
Mkhitaryan, though, is willing to accept blame for his underwhelming period at Manchester United.
“I don’t want to find excuses,” Mkhitaryan told Sky Sports.
“I don’t want to blame anyone…I am starting a new chapter in my life, in my football career and I am very happy to be here.
“I will be pleased to achieve more than I have done in Manchester, of course. I don’t have anything to prove to anyone. I just have to enjoy myself, do my best and at the end I will see where I can reach.”
Mkhitaryan made three assists in Arsenal’s 5-1 win against Everton in the Premier League last weekend as the Gunners number seven excelled on his home debut.
His former Dortmund team-mate Pierre-Emerick Aubameyang completed a club record £56m move to Arsenal in the January transfer window.
