The 28-year-old left the Bundesliga as the players' player of the year, but Manchester United boss Jose Mourinho used Mkhitaryan sparingly.
As reported by the Mirror, when about those rumours in his pre-match press conference, Wenger responded: "He has a very professional attitude and overall I think that is what you want from every player".
Mkhitaryan reveals Mourinho is more tougher whereas Wenger is more understanding of a player.
How did Mkhitaryan get on against Spurs?
That's according to the majority of social media after the Armenian's abject display against Spurs in the north London derby.
Henrikh Mkhitaryan is living a dream at Arsenal after being reunited with close friend and "the best teammate" he's shared a dressing room with Pierre-Emerick Aubameyang.

The 29-year-old also found the net in Arsenal's 5-1 victory over Everton and he appears to be flourishing under Arsene Wenger's management style.
The first half was a close, well contested affair with neither side able to create many clear-cut opportunities so the two teams went in at the break level at 0-0. But Wenger hopes that his own clever jumble of players will pay off on the pitch.
If one moment summed up Mkhitaryan's performance today, it was this utterly awful cross during the first half...
"That's the difference [with Man United manager José Mourinho]". But the Armenia global is proud of his body of work at the club. "There are loads of points still to play for, so we need to look forward".
But maybe the Arsenal fans are right.
Ahead of this game, Pochettino told the club's official website: "It will be an incredible game and we are so excited because we know what it means to play the derby".
