He's been dire since his return but one of the big problems we have is that we really don't have enough other options for a reliable source of goals up front.
Giroud scores about three in a batch before going on a 8 or so game drought, Theo is hit and miss, Ozil has a slight bit of the Hleb's about scoring, Ramsey's lost his goalscoring touch and Ox seems incapable of using his talent to score goals.
Oh how I cry for the days when you had Henry, Freddie and Pires all contributing double figures every year.
