We should have enough money in the summer to strengthen our attack (and with money being generated from sales as well). I think Bendtner will be fucked off back to London, and the chances of us picking up anyone decent in January are remote (Llorente and Drogba being the likely options, and in that case, the outlay on both of them will be minimal in terms of transfer fee).
I don't really rate Lewadowski, and highly doubt we are going to acquire Villa. I'd love Suarez in the summer, but that depends on how strongly he wants to leave England, play in Italy, and particularly play for us.
