Do "players" get jealous?

Ok, so I'm bored lol! Me and my friend were having a discussion about players, and I said "If a guy who is known as a "player" gets jealous of a girl and the guys she talks to and hangs with then I think he has genuine feelings for her and is considering a relationship" My friend said "No! I disagree! Players can get jealous too, doesn't mean they want a relationship or anything"

Jealousy indicates insecurity, but it also indicates feelings and emotions towards that person, so in my opinion if a guy who sleeps around and is a "player" has jealousy towards a girl then I think he has genuine feelings and wants a relationship, cause why would a player get jealous if they just want to get laid? That is their prime focus, so to me if a player gets jealous then he obviously wants more out of the relationship and he just doesn't want to get laid, but my friend thinks the opposite. So do you agree or disagree? What are your thoughts on this? Pleas ebe detailed, thank you so much! :)
