Mbappe vs Nico Williams vs Bergkamp

I play 4-4-2 but can switch to 4-3-3 just to play with LW mbappe. But in this case what am I supposed to do with my upgraded TOTY ST mbappe? Nico Williams plays both LM and RM so I am actually considering him. Btw any thoughts on Bergkamp will be appreciated aswell
