Graham Potter’s men kept their champions league hope alive in an important 3-0 win at Stamford bridge.
In the must win game, Wesley Fofana scored the first goal for the club on his Champions League debut to give the Blues a great start.
Unfortunately, he quickly fell from grace when the defender appeared to suffer a knee injury and had to be replaced.
Following a second-half goal by Pierre-Emerick Aubameyang off a pass from Reece James, the Blues’ lead was increased.
The Right back, who was outstanding in the game, then added a goal of his own to give Potter his first triumph in a European competition.
With the crucial victory, Chelsea moved up to second place in the group, one point behind Salzburg, which defeated Dinamo Zagreb in Austria.
Chelsea has won 36 of their last 52 group stage home games in the UEFA Champions League and drawn 14 times.
