LL is coming in the summer, Gio is Juve-breed and deserves a place on the team though he still has not really proved himself. Either way, Gio should stay at least as a rotational player. Vucinic is our best striker so far, quality wise and for his contributions in general IMO. Quagmire is our best scorer so far if i recall correctly, Anelka will hopefully leave after his loan spell and the same goes for Bendtner.
Matri has so far contributed with hard work, good forward runs but little effectiveness and only four goals. Though both Martri and Quagmire deserves the acknowledgement that they are working facing an uphill considering how little Conte has shown his belief is in them. They seldom get regular playing time to work on their form and confidence that his so lethal for a striker. This has obviously affected Matri who every time he has scored has spoken openly mostly of the relief of scoring and that his self-esteem has been really poor. Naturally he will struggle. Anyway, as much as I have liked Quagmire before, the alessio incident has annoyed me. Moreover he has been flirting with Zeman and left hints of wanting out. Thus, Quagmire needs to leave this summer despite being our right now only decent box-striker.
This leaves us with LL, Matri, Gio and Vuc this summer and we are hoping to get another WC striker. If Matri wants to stay as a fifth-sixth striker I don't mind, he is definitely good enough for that. But I don't think he will want to. Hence, to conclude, I don't think Matri will be around when next season hits off.
Edit: Forgot that
Gio has scored a lot more than Quag. My bad.
