Jackson, a £32million summer signing from Villarreal, netted his first goal for the Blues in the recent 3-0 win over Luton.
The Senegal international has shown promising signs so far this season but you wouldn't have thought so by his EA FC rating.
EA Sports has released its player stats ahead of the upcoming video game launch and much like teammate Thiago Silva, Jackson appeared disappointed with his rating.
However, there was no sympathy from Madueke who instead piled in on his new teammate, teasing him about his numbers.
Jackson was handed an overall rating of 77 which was broken down into six variables based on his game.

The 22-year-old was given 85 for pace, 79 for shooting, 69 for passing, 76 for dribbling, 35 for defending and 78 for physical.
In FIFA Ultimate Team, Jackson would be a common card rather than a rare card.
Footage released by Chelsea shows Madueke holding a life-sized card of Jackson's stats with a very unimpressed look on his face.
He then tells the striker: "It's not even a rare G. It's a non-rare bro. You see the shiny thing? You ain't got that bro."
