I have done over 600 PL Upgrade Packs to get some blue player, unfortunately I had no luck in these packs, then I opened a rare two player pack and got Ninja Turtle Mbappe.
In the first games it was very difficult to control his speed in combination with his strength (with Marksman 96) it is impossible to push him off the ball.
His shooting feels like 5* WF he scores bangers with left and right.
+ combination with strength, speed and dribbling
+ shooting inside the box
+ double tapping sprint button = up up and away
- maybe his price ?!
