Maybe a few of us got over-excited by his early season form. But some of his touches and link-up play was fantastic; it wasn't just about the midfield, he was crucial in making them tick as well. In the recent big games, it's not just Giroud but many players who have failed to get us going.
I never feel confident that Giroud could create something out of nothing or take a difficult half-chance to win us a big game, and so buying an excellent striker is the easiest way to improve our team. But I think he is a lot better than what he has been showing in the last month or so. We seem to be asking a lot of Walcott...maybe he'll stretch opponents, maybe he'll make Ozil play better, maybe he'll score a shedload of goals, but that one-touch lay-off thing that Giroud does is particularly useful for runners so Theo should help.
