Super defenders have their place and yes we need some but they don't score goals and this team has few goals in it, unfortunately. Super strikers do and yes that's on our shopping list as well but trading one for Ayew makes no sense to me as we know for a fact that he has goals in him. He's also a little more versatile.
I'm not sure where this trade idea has come from to be honest but if we lose Ayew then fine, but that's 10 goals we need to find next season before we start. If we lose Siggy, it's even worse. I'll be disappointed to lose Ayew but if it is a direct swap (there's no evidence of that being the case right now) then we have to get someone in who is proven to score goals at this level. I can't see that happening.
Now, if we get a decent striker and still have Ayew and Siggy on the pitch I'd be very happy indeed. Paloschi is OK and a busy little player - a good backup maybe - but I'm not convinced he's ever going to be prolific.
