Chelsea 2-1 Brentford - Clinical Jackson stars for Blues
Nicolas Jackson was widely regarded as a player with raw ability during his first season at Chelsea last term.
However, there are now clear signs that the Senegal international is realising his full potential.
The 23-year-old's numbers around shot accuracy and conversion rates have all been trending in the right direction from 12 months ago.
And he now appears a more assured and accomplished all round player.
The manner in which he scored this ninth goal, of what is rapidly becoming a prolific campaign, only served to underline his progression.
Striding on to Enzo Fernandez's searching pass he looked like a player with all the time in the world as he stood up Brentford central defender Ethan Pinnock before finding the bottom right corner with an unerring effort.
If he can continue in the same vein over the coming months, he could prove to be the difference for Chelsea in a title race that is suddenly sparking back into life.
