Trippier is much better than Alexander Arnold (currently) imho and probably better than walker from attacking positions. Not too sure about walker as part of a back 3 though as his defensive strength is making recovery runs and he won't be doing much of that as a cb.Only change I’d consider is Trent over Trippier.
Or Even Dier at CB and Walker at RWB
