This is the fourth consecutive league defeat for the "blues" with a goal difference of 0:11. The last time Chelsea suffered four league defeats in a row without conceding a goal happened four decades ago, which clearly shows the crisis Liam Rosenior's team is in. The giants from north London are dangerously risking their place in Europe, and currently hold sixth place (the last one that guarantees the Euro scene, together with Brentford and Bournemouth with 48 points each).
On the other hand, the "Red Devils" came within a whisker of qualifying for the Champions League and also ended a mini-streak of two games without a triumph.
The decisive moment came in the 43rd minute when Mateusz Cunha headed home Bruno Fernandes' assist. It was the United captain's 18th assist of the season in the Premier League and he is now just two assists away from equalling Thierry Henry and Kevin De Bruyne's record, and three away from becoming the most assists in a single season in the English top flight.
True, the home team was not lucky tonight, as they hit the target on three occasions.
Earlier, Tottenham drew with Brighton at home - 2:2.
The "Pijevci" led twice, but the "Galebovi" managed to pull out a point in the fifth minute of stoppage time with a goal by Žoržinj Ruter.
De Zerbi's team remained in the danger zone with 31 points, one less, but also a game more than West Ham, who are first above the line.
At 4 p.m., Bournemouth celebrated against Newcastle away (2:1), while Leeds routinely defeated the regrettable Wolverhampton in front of their fans (3:0).
In the first match of the day, Brentford and Fulham played out a goalless draw.
