He made his debut for Sunderland on 21 September 1929 against Arsenal in a 1–0 loss at Roker Park. He was part of the 1937 FA Cup Final winning side against Preston North End. In his career at Sunderland, Gallacher made 309 appearances and scored 108 goals in all competitions. He helped the "Black Cats" to win the First Division in 1935–36, scoring 20 goals in that title winning season. He then moved on to Stoke City in December 1938 just before the World War II. He only managed to play four matches for Stoke due to injury and left at the end of the 1938–39. He then played in Ireland for Coleraine and Cork United before signing for Cheltenham Town in September 1948 playing 8 games before leaving.
 Link Information: In 1929 the old wooden grandstand was demolished and replaced by a new Main Stand, which was designed by Archibald Leitch, whose influence, the criss-cross lattice work, can still be seen at Ibrox (Rangers), Home Park (Plymouth Argyle) and Goodison Park (Everton). Fragments of the iconic lattice work would later be used to separate parts of the car park at the Stadium of Light. The work on the new Main Stand nearly bankrupted the club. By this time the official capacity of Roker Park was 60,000 Question: What was the seating capacity at Roker Park in 1929?
[EX A]: Answer: 60,000

[EX Q]: Passage: In the second qualifying session, every driver set a lap on the option tyres except two. Lewis Hamilton still managed to take his McLaren into Q3 with the sixth fastest Q2 time on the prime tyres, and Pastor Maldonado, who did not set a timed lap. It was notable that Red Bull Racing and Ferrari needed to use options when Hamilton could use primes. Jaime Alguersuari – a man who had come from far back to score points a few times in , like his teammate did at this weekend set the slowest Q2 time and dropped out on the same row as Rubens Barrichello's Williams. Neither Renault made the top 10, Vitaly Petrov in 12th and Nick Heidfeld in 14th. One Force India and one Sauber failed to make the cut – Kamui Kobayashi (13th) joined Heidfeld on row 7, and similarly Paul di Resta just missed out with 11th.
