“If there’s one result that sums up the crazy, unpredictable end to this Premier League season, it’s Chelsea’s 2-1 defeat at home to Sunderland. That was Jose Mourinho’s first home league defeat as Chelsea manager, after 78 games, and proved crucial at both top and bottom. Chelsea’s chances of winning the league title took a huge blow, while Sunderland continued their great escape. However, to a certain extent that result was typical of their campaigns, because Chelsea and Sunderland are the two sides in the division that have collected more points against top half sides, than against bottom half sides.” Zonal Marking
