The French striker hobbled off at the end of the Gunners’ 2-2 draw with Everton on Saturday – in which he netted a late equaliser – with an ankle injury, and is now facing a number of weeks on the sidelines.
Although the burly striker hasn’t been a guaranteed starter so far this term, Arsene Wenger is very short on cover in the role, with Yaya Sanogo – who is yet to score a Premier League goal – the only orthodox option to cover.
Alexis Sanchez and Lukas Podolski can play as centre-forwards, but both are more known for deeper roles.
Although the full extent of Giroud’s problems are not yet clear, a lengthy period out could force the club into a late flurry of transfer activity to get a new goalscorer in.
With the window set to close in under a week, Arsenal will be low on options, with Edinson Cavani and Radamel Falcao two names on a short list.
However, the former may not be available with PSG having missed out on Angel di Maria, while the latter will only be available for a loan deal for a massive £20m fee.
