With scores like that I don't see a reason to replace him right now. He has an average of 8. Sometimes it is not all about the scoring. For next season you might be able to get a striker with 39 quality. This striker will not get that quality soon so that would be an improvement. Unless you have a lot of greenpacks to spare I would sell him and use the money to get one or two new good strikers. I would love to buy him next season from you for my new team though I am only level 1 with that one right now though.

But a striker with an average of 0,65 goals per match and 0,5 assists is a good player if you ask me.
