I don't know how you'd react to losing that heavily at home - as you say, digger, it must be soul destroying. On the other hand it can only get better!
Bournemouth did once beat us 7-2 at Millmoor - but we had our 'keeper carried off with concussion early on (Seamus McDonagh) and played Trevor Womble at one bit in goal and I believe Carl Gilbert took over too!
One of my first Boro matches (8-0 Sheff Wed).
Graeme Souness scored a hat-trick if i remember rightly , and we'd beaten Notts County 4-0 in our previous home match.
Went into the top flight (Jack Charlton's first season as a manager)
