The secret of Aubameyang and Lacazette's chemistry
Sky Sports' Michael Hincks analyses what makes the duo's bond so special.
"From their trademark hand-shake celebration to photos of the pair beaming in training, Aubameyang and Lacazette evidently have a rapport on and off the pitch - but that did not always seem likely.
"Lacazette and Aubameyang were the centre forwards at their respective former sides. Lacazette started 28 Ligue 1 games up front in his final campaign at Lyon, while Aubameyang was Borussia Dortmund's first-choice in 16 of the German club's 20 Bundesliga games before he joined Arsenal last season.
"As a result, there was a belief something had to give when Aubameyang arrived at the Emirates, with Lacazette's importance to the club - and his own future - set to come under scrutiny.
"But that has not been the case, with Lacazette insisting he never considered leaving in the summer, and instead thriving in the relationship brought about from Aubameyang's move to Arsenal.
"Of the many tasks Emery took on from Arsene Wenger when becoming Arsenal head coach in the summer, it is evident his man management of Aubameyang and Lacazette has been a success. The proof is in the smiles still present on the pair in mid-April.
"A long run out of the team could have affected their confidence, but instead, Emery has carefully rotated and considered what the best approach is for each game.
"And that partnership, whether they start together or not, will need to maintain its strength as Arsenal enter the final stages of the season fighting for Europa League glory and a finish in the league's top-four."
