Elneny and Partey both injured 1 week before deadline day. And now we have Timber injured and K.Tierney leave and maybe Holding and Cedric leave, so they have to find a new defender. The reason they let K.Tierney leave i think they are working behind the scence to get a new defender or they think 6 defenders are enough
They weren't season ending injuries either. I think it was a couple of months at worst. I think they're setting themselves up for failure if they don't bring in another CB or LB.
