A goal each from the Alexes - Iwobi and Lacazette - helped Arsenal to recover from their 3-1 defeat at the hands of Man City with a much-needed win, even if a late Sead Kolasinac own goal took the shine off the result.
The Gunners are now fifth, one point behind a resurgent Manchester United who have been in great form since the appointment of an interim manager, Ole Gunnar Solksjaer who took over from Mourinho.
"I just think Emery is really struggling to find a solution to his defensive problem, especially with his side's injury issues - although Shkodran Mustafi should be fit after limping off against City".
And he will be encouraged by the fact Arsenal have won all three of their Premier League meetings with Huddersfield.
"A clean sheet is important, but our main worry is to win", Emery said.
"Our motivation is very great, every player wants to win every match".
"It always seems to happen when we are two goals in front, so maybe we are losing a little bit of concentration because we feel too comfortable when the games are coming to the end". Judge us by our work and what the players are doing and this makes me proud.
"Everybody worked very hard and we were unlucky to concede the goal but overall it was a deserved win".
