I have like 5 million, which player should I buy?

I am looking to buy some players (or a player if he worth it) with my 5 million in Fifa. Who should I buy? Any suggestions?

I’d prefer Mbappe who costs like 4 million or something. He is fast, has a good pace and the shots are pretty powerfull. So, If have an attacking strategy, you could utilize his skills pretty good. So, Kylian Mbappe is my suggestion.
