Brothers Jack and Bobby Charlton were heroes together on the pitch when England won the World Cup in 1966.

But this Second Division match between Boro and Preston seven years later put the siblings head-to-head at Ayresome Park.

It was the first ever managerial showdown in English football between brothers. Both Charltons had moved into the dugout in the summer of 1973, with Bobby joining Preston and Jack arriving on Teesside.

Come December, Jack looked like he was realising the potential of a Boro side that had flirted with promotion to the top flight in previous seasons - his side were 17 games unbeaten. Languishing at the bottom end of the table, Preston were struggling to avoid exiting the division in the opposite direction.

The elder Charlton’s side dominated this one in typically efficient fashion, David Mills and veteran midfielder Bobby Murdoch putting Boro two-up within 22 minutes.

Classy youngster Graeme Souness added gloss to the game with a third, his first for Boro, with just a minute to play.

It was a glorious season for Boro. The unbeaten run extended to a club-record 24 games, winning the title at a canter with a league-record number of points.

Preston, on the other hand, were relegated that year, with Bobby to be replaced by Darlington-born Harry Catterick in 1975 - the end of his interest in management bar a caretaker spell with Wigan nearly ten years later.
