'There could be mistake after mistake': Paul Merson admits he 'worries for Arsenal' and fears defenders will struggle to keep concentration levels behind closed doors after David Luiz howler in practice defeat by Brentford
Paul Merson admits he worries for Arsenal playing behind closed doors when the season restarts and fears their defenders could make 'mistake after mistake'.
The Gunners suffered a shock 3-2 defeat by Brentford in a practice match at the Emirates this week, with David Luiz chief among those responsible for individual howlers.
And the former midfielder believes the Gunners players will struggle to keep their concentration levels high without fans in attendance.
