First of I've got to mention that if you are not a Manchester United supporter or love Rashford, I do not recommend doing him. Very expensive sbc, and it's only a +3 from his gold card.
If you do decide to do him then you are in for a treat. This guy with a finisher chemistry style is very hard to defend against. His 3* wf doesn't seem to matter too much with his 98 finishing (with chem. style). He's got H/L work rates which is an upgrade from his gold card which is M/L. This guy makes very good AI runs, has a decent passing ability and good physicality, so harder to get off the ball.
