We are all assuming that Tierney will leave mainly because he doesn't suit the inverted full back role, it did occur to me that might not always be the case.
Successful teams get worked out and to sustain success they need to change things up. Man City and Liverpool both evolved quite a bit during their 4-5 year tussle with each other.
I still think he is a dead cert to leave though all the same
I agree with what you’re saying. I like having both KT and Zinny as they provide complete different styles, it gives us more variety. I’d like another “traditional” style fullback to come in to replace KT.
