From Herbert Chapman on Football, a posthumous compilation of his Sunday Express articles published in memory of him in 1934:
I am always sorry for clubs who have to act hurriedly in seeking a new player, for under the most favourable conditions it is a tricky business and demands the closest consideration. It is not enough that a man should be a good player. There are all sorts of other important factors which have to be taken into account. This takes time. The longer I have been on the managerial side of the game, the more I am convinced that all-round intelligence is one of the highest qualifications of the footballer. I suppose one of the best teams there has ever been was that claimed by Newcastle United for ten years or so before the War and that part which so many of them have since played in the game indicates that they were intellectually above the average.
