Manchester City have scored eleven goals in first halves and 22 in the second.

Reading have scored six and eleven. Bristol four and five.

Arsenal are ranked fourth with 19 goals in the first half and 23 in the second (55%).

The bottom team in that category is Everton with six goals in the first half and only one in the second.

The reverse statistic is also available –  the number of goals conceded in first and second halves.

Arsenal are second from bottom with 43% of their goals conceded in the second half with four and three.

Birmingham City are top with 88% of their goals conceded in the second half with one and seven. They clearly drop their performance level after half-time.

Manchester City are second with 67% of their goals conceded in second halves. It is exactly the same percentage as their goals scored.

Brighton are in third place with 61% of their goals conceded in the second hlaf with 11 and 17 goals conceded.
