Caps: 1 (of 10)
In the summer of 1966, Benny Fenton went shopping for some new additions with the proceeds from the sale of goalkeeper Alex Stepney. The Lions' defence had been pretty rock solid the previous season but the Millwall manager still felt that it would be useful to strengthen the squad. After all, one never knew what was around the next corner.
One of those summer signings was Arsenal defender and Northern Ireland international Bill McCullough. McCullough had made over 250 appearances for The Gunners and Fenton felt he'd be the perfect cover for fullbacks John Gilchrist and Harry Cripps. As it turned out, Fenton got it spot on when the ever-popular Cripps picked up a long-term injury.
McCullough filled the breech with aplomb and despite only playing 19 games for The Lions in his one season with the club, fans still remember him today as a useful defender who could've easily played a lot more but for the form of the players in front of him.
Born in Larne in 1935, the left back had already been capped nine times by his native country, having made his debut back in 1961. At the end of the season he made his tenth and final appearance for Northern Ireland as England run out 2-0 winners in the Home Internationals at Windsor Park.
