We're not going to sign a striker of world class calibre, lets just accept that. I'm becoming more and more certain that Mandz is going to stay at BM. He's the only striker that I could've seen us signing and even them, I give us like 20% chance of signing him because chelsea are obviously going to sign one. Costa is likely to become available given Atletico's financial worry but he really won't suit us anyways.
We're going to have to make our own world class striker and well, it's what teams are doing. Last season, Costa was a nobody. Lewandowski nearly signed for the prodigious Blackburn Rovers of Lancashire Arte et Labore.
