Arsenal have been handed a huge injury blow ahead of the north London derby against Tottenham Hotspur in the Premier League.
The Gunners have had a good start to the top-flight campaign, and they are currently four points ahead of second-placed Manchester City.
The London heavyweights have coped well with injuries during the early part of the season, but have now suffered another couple of setbacks.
Riccardo Calafiori has recently returned early from international duty with a hip issue, which ruled him out of the World Cup qualifier against Moldova.
The Gunners have sustained another blow with Gabriel Magalhaes suffering an apparent groin injury during the friendly against Senegal today.
The Arsenal faithful were excited by the prospect of Gabriel turning up at the Emirates Stadium with Brazil, but his game unfortunately ended early in the 64th minute.
It remains to be seen whether the 27-year-old will be fit for the north London derby against Spurs next weekend. Arsenal host Spurs at the Emirates on November 23.
The £66 million-rated star has been ever-present in the Premier League this campaign. He has played a big part in the early months with some crucial goal contributions.
