The Frenchman opened the scoring with his first goal for the club, ahead of Pierre-Emerick Aubameyang and Reece James netted while the Blues defeated AC Milan 3-0 in a dominant display at Stamford Bridge.
It puts Chelsea back on track to qualify from Group E after a slow start to their European campaign, but it came at a cost when Fofana was forced out in the first half with what appeared to be a knee injury.
The 21-year-old was pictured leaving Stamford Bridge on crutches and with a brace on his right knee, while Potter was unsure of the seriousness of the injury.
“We’ll have to scan it tomorrow to see what it’s like,” Potter said.
“Nothing to report at the moment, but that’s the only disappointing thing about the evening.”
Other than that, it was pretty much a perfect night for the Blues, one that left them second in Group E and just a point behind RB Salzburg taking the lead.
While a trip to San Siro for Chelsea is on the agenda, and Milan certainly need to improve on their own turf, the emphatic nature of the Stamford Bridge win was a huge boost for Potter and his players.
“It was a good night for us,” Potter told BT Sport.
“I loved the attitude and commitment of the players and it’s a very important win for us.”
“We started a little nervous for five minutes, which was probably because we wanted to do it so well, so much. But then you saw the appetite of the players and we took control of that.
“Of course the first goal was important and then we had to start a bit on the back foot in the second half. We suffered a bit, which is good, and then we scored the second goal, which gives us a bit of a breather.
“In general, I can’t complain. Clean sheet, three goals, great player personality, really good.”
