I like the tournament idea more than anything else suggested so far, could become a staple thing for a few years including a raft of previous clubs (whoever was available)?
PSV, Barcelona, Sporting, Porto, Us, Ipswich, Fulham and WBA aren't exactly a bad pool to choose from!
Obviously the venue could change each year, along with the participants. It'd be a bugger to organise, but could be a very nice touch for a very good man.
the "sir boby robson tournement"
it should get held at the stadium of the previous winners, first one at the toon.
As long as you're not in charge of advertising such an event.
