It's a goodly morning at last as we enjoy the 2-0 win over Chelsea on Saturday. Unai Emery changed things up and it paid dividends. We saw a strong defensive performance, a midfield diamond which worked really well, and we created lots of first half chances. We analyse the game, whether it's an approach we will continue in the weeks ahead, and if it's a result we can now build on. Then we answer listener questions and discuss the implications of the injury sustained by Hector Bellerin. We have options in the squad but who should replace him? There's FA Cup team selection, Calum Chambers Arsenal future and lots more.
