CALUM AND COLLECTED
Calum Chambers has edged his way into our Premier League starting XI and, on this form, he will be hard to dislodge. Chambers handled Daniel James well at Old Trafford at the start of the week, and he ended the week by keeping Josh King at bay to help us record a precious clean sheet. It was a performance of poise and passion, silky first touches mixed with tenacious tackling, and one brilliant intervention inside his own six-yard box to deny Bournemouth an equaliser. Chambers had 20 more touches than any other Arsenal player, contested the most tackles and the second-most duels. He got forward too - only Aubameyang had more shots on goal for us, but nothing as spectacular as Chambers' volley from Ceballos' cross. That flew wide rather than in, but the fact Chambers took it on shows how high his confidence is right now.
DANI STANDS OUT
Dani Ceballos didn't finish this game but he was a big influence on it. The Spain midfielder is still best remembered for that breathtaking home debut against Burnley but, although he wasn't quite as eye-catching against Bournemouth, Ceballos exerted a similar amount of authority. He wasn't a goal threat but he led our attacking stats with three key passes, the highest pass accuracy (86 per cent) and the most passes in the opposition half. Defensively, Ceballos is coming along nicely too; no one in our team could match the 11 times he gained possession. Our loan signing from Real Madrid has had to adapt to the physicality and pace of the Premier League but on this evidence his acclimatisation is going well.
CASE FOR THE DEFENCE
We haven't had many 'One-nil to the Arsenal's of late, and our back line will relish a first Premier League clean sheet since the opening-day win at Newcastle. Bournemouth came on strong in the second half on Sunday, delivering nine crosses from open play compared to just one in the first half, but we repelled them all. Chambers and Guendouzi made last-ditch challenges to preserve our clean sheet, and the whole team grafted off the ball. Pressing was a key component of our first-half dominance - Aubameyang and Pepe forcing defensive errors that kept us on the front foot - and of course it was a defender who scored the winner. David Luiz has his first goal for us since signing from Chelsea, and it's no surprise that it came at the Emirates - 11 of his 12 Premier League goals have been at home.
