Re: Kennedy vs. Barnes.
I'd sidestep that by having a 3 man midfield with Souness, Ray Kennedy and Terry Mac or SG (I'd probably plump for SG). You could then have a front three of JB, Rushie and Kenny. Lots of flexibility there, you could easily switch between formations.
You have to have Kennedy in there. On the Liverpool managers dvd Bob Paisley says that for 3 or 4 years Ray Kennedy was the best mdfielder in Europe.
(Rest of my side would be Clem, Smith right back, Nicol left back, Hansen & Lawrenson. Nicol won Player of the Year whilst playing fullback. Can't think of another precedent for this).
