The was Giroud is playing I am more than happy with him as our first choice CF, but there is no guarantee he can keep up the form over the whole season. We need someone to challenge him for that first team place. Our squad is brimming with creators but we only have a handful of consistent goalscorers. Podolski is an option but he hasn't really done well for us as the main striker in a 4-3-3. Bendtner two or three steps down from Giroud and Sanogo is still in nappies.
It doesn't have to necessarily be someone of Suarez or Lewandowski's ilk, but I'd prefer someone with a proven goalscoring track record.
