The former Dortmund striker joined last month in a bumper £55-60 Million deal, and marked his debut with a goal against Everton last week, and was kept in the starting line-up to take on Spurs this weekend.
Lacazette was signed in the summer for a club-record fee from Lyon but has struggled to maintain form as the season has gone on.
Lacazette was introduced on 65 minutes as Arsene Wenger tried to get more attackers on the pitch, but it took the France global a good 25 minutes to get into the game following his inclusion.
With Arsenal sitting in sixth place and six points back of the top four, Bellerin bemoaned a lack of initiative as the Gunners controlled possession in the first half.
"Once the game has started, these guys have top-level experience", Wenger said of Mkhitaryan and Pierre-Emerick Aubameyang.
Winter Olympics 2018: North and South Korea hold landmark meeting
USA officials have not ruled out the possibility that the vice president might meet a North Korean official at the Olympics. But the North was welcomed with open arms to what South Korean President Moon Jae-in called "Olympic games of peace".
Apparently Mkhitaryan is "soft".
And Mkhitaryan, when asked abut his time at United, made it clear that he wanted to look forward rather than back.
"It's a bit too early to compare him to the best player ever who played here", Wenger said.
We're sure several former players would agree with Mkhitaryan's assessment of the different managerial techniques of both Wenger and Mourinho.
He's clearly a flat-track bully, unlike, say, Romelu Lukaku. I can understand him from step one and hopefully for the next games we are going to achieve more.
Also, Mkhitaryan is at fault for Arsenal's inconsistency, because, before he arrived at the Emirates, Arsenal were a reliable team, who never followed a big win with a poor performance.
