#4 Despite average individual display, Lacazette's presence key
After Alexandre Lacazette's suspension was surprisingly reduced on Wednesday, news of his inclusion proved a welcome boost for Arsenal's chances of progression. Although it was an average display by the forward's high standards, you could tell why his presence alone was key too.
Having scored or assisted in seven of his last nine outings prior to this encounter, he was a constant threat - just like against Tottenham and Manchester United, where he managed to hassle and harry the opposition into making mistakes.
His infectious attitude sets the tone and defensive work out of possession stifled Rennes' tactics. One key pass, dribble, aerial duel won, and fouled twice with not many touches on the ball, his match stats don't stand out.
However, he did the dirty work which typifies his relentless work ethic and is another reason why he quickly became a fan favorite in North London, proving there's more to his game than just goals and assists.
