I picked up Alexander Isak for my 80k starter team to be a strong hold up striker. Since then he has been amazing for me, his dribbling, while on paper is bad, he can dribble past defences by himself if you learn how to use him. His positioning and movement with dybala up top is top tier and makes scoring easy. Along with this, his shooting is great and hit the ball really hard. If you are looking for a cheap strong striker I would consider picking him up and link him to Mikel Merino in midfield.
Dribbling (to an extent)
Skill moves (I didn't use much but they're there)
Passing (To an extent)
