XHR request URL says does not exist when attempting to parse it’s content

You have several problems:

• the url should be http://www.whoscored.com/stageplayerstatfeed
• wrong GET parameters
• missing important required headers
• you need response.json(), not response.body

The fixed version:

import requests

url="http://www.whoscored.com/stageplayerstatfeed"
params = {
    'field': '1',
    'isAscending': 'false',
    'orderBy': 'Rating',
    'playerId': '-1',
    'stageId': '9155',
    'teamId': '32'
}
headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/36.0.1985.125 Safari/537.36',
           'X-Requested-With': 'XMLHttpRequest',
           'Host': 'www.whoscored.com',
           'Referer': 'http://www.whoscored.com/Teams/32/'}

response = requests.get(url, params=params, headers=headers)

fixtures = response.json()
print fixtures

Prints:

[
    {
        u'AccurateCrosses': 0,
        u'AccurateLongBalls': 10,
        u'AccuratePasses': 89,
        u'AccurateThroughBalls': 0,
        u'AerialLost': 2,
        u'AerialWon': 4,
        ...
    },
    ...
]
