Well the thing is with replacing Milner, we're going to have to see another workhorse, someone who can run until they drop which is preferably a threashold of about 120 minutes as opposed to 60 *cough Petrov cough* but I would be happy with a youngster filling Milner's boots should he leave.
I would be inclined to agree with you Qwpzxjor1 that we need a bit of experience up front.
