Arsenal added to their backline at last, but left it late, bringing in David Luiz from Chelsea and Kieran Tierney from Celtic just before the close of the transfer window. I'm joined by Andrew Allen and Tayo Popoola to chat about the signings, and the transfer window as a whole, before we get a Celtic point of view on the new left back. Kevin Graham is a Celtic fan who has watched Tierney establish himself in the team, so we get some insight into what kind of a player he is, and what he can bring to the club. Then there's a chat with James about our deadline day business, the departure of Alex Iwobi to Everton, and Eddie Nketiah's loan move to Leeds. It's a bumper episode, enjoy.
