So, which performers stood out?
✔ Reece James: 7.7
Quite a lot of Chelsea‘s play went down the right-hand side on the night, and this was largely due to the presence of Reece James, who displayed superb athleticism to get up and down the flank all evening.
He was effective in both attack and defence, as he sent 14 passes into the final third and sent more crosses into the box than any other player in the match with seven.
Defensively, he won 6/11 duels, 100% of his tackles (4/4) and 100% of his aerial duels (2/2).
✖ Jesus Corona: 5.4
Jesus Corona didn’t have a good night for Porto and was desperately ineffective in the final third.
He had one shot on goal which went wide, but his lackadaisical display in possession was the worst aspect of his game as he gave up possession no less than 22 times.
On one particular occasion when he lost possession, it allowed Chilwell to run through on goal and score. A bad mistake.
The former Rennes stopper made five great saves on the night to deny Porto, while he also took the pressure off his defence with 11 ball recoveries.
As ever, Tuchel asked his side to play out from the back, and Mendy was key to this as he completed 27/32 attempted passes.
