From the moment the Premier League fixture list was announced, Unai Emery must have known he was in for a tough start.
"It's down to me to prove a point to Arsenal that they were wrong to get rid of me", the 26-year-old Wilshere told West Ham's match-day programme.
Unai Emery had stationed Aaron Ramsey in his starting line-up against Manchester City in Arsenal's opening game of the new Premier League season.
Emery has had just over a month to work with his new players.
Mkhitaryan added on a new era under Emery after 22 years of life in north London under Arsene Wenger: "We have a new manager and are trying to adapt to his philosophy and also his demands". "But times change, people move on, and I think it was his time to go". It's benefiting me a lot more.
"In our process, we are going 38 matches against all the teams - whether you are playing against Manchester City, it's the same as if you're playing against West Ham on Saturday", he said.
Mkhitaryan and team-mate Mesut Ozil have faced calls to be dropped by several pundits, including former Arsenal midfielder Paul Merson.

But quarterly reports on results are distinct from the so-called earnings guidance that company executives provide as a forecast. Others said that the prospect of fewer financial reports could exacerbate price swings around earnings or fuel insider trading.
One Arsenal fan tweeted: "Just a pity he can't do it consistently in front of goal." while another asked the club's official Twitter account: "Can we focus on scoring actual in game goals".
"Xhaka would have stayed on under Wenger, so would Ozil, and what's that said now in that dressing is that "no one's going to be safe, if you don't do what we need you to do, you're coming off" and I'm pleased to see that".
"He hasn't got the players to have a 20-yard gap between defence and attack, working hard".
"I don't know if the current crop have gone past being able to learn that way of playing".
Arsenal striker Pierre-Emerick Aubameyang has disclosed details regarding the club's fastest player statistics.
This means Aubameyang will start against West Ham while Lacazatte will be benched for third straight league game.
