Former Arsenal midfielder Fabrice Muamba has taken a swipe at Mathieu Flamini after his disappointing performance against Liverpool, questioning what the Frenchman actually brings to Arsene Wenger's team.
The retired footballer openly criticised the 30-year-old on Twitter following his dreadful first-half display at Anfield on Sunday, where Flamini was lucky to avoid being sent off after clearly committing two bookable offences.
The former AC Milan star took the brunt of Gunners supporters' frustration after a tepid opening exchange which left the visitors scratching their heads at how they had managed to go in level at the break.
Liverpool dominated from the first whistle, but were unable to make their dominant possession count until Philippe Coutinho finally put the hosts ahead with a well-taken goal from the edge of the box.
However, Reds fans' joy was short-lived as minutes later Mathieu Debuchy converted an Alexis Sanchez free-kick, getting above Martin Skrtel at the back post to bring the game all square just before the interval.

But, despite the fortuitous half-time scoreline from Arsenal's perspective, Flamini's poor performance was not lost on Muamba, who blasted the £65,000-a-week star's general contribution since returning to the Emirates Stadium from Serie 'A' two summers ago.
Wenger opted to bring Flamini back to north London on a free transfer upon the expiry of his contract at the San Siro, but he's struggled to ever really nail down a regular place in the side after a series of unconvincing performances that were epitomised by his first-half display on Merseyside yesterday.
With Mikel Arteta, Jack Wilshere and Aaron Ramsey all sidelined by injury, Arsenal's weakness in the middle of the park has been highlighted even further, leading to louder cries from the Emirates faithful for Wenger to re-enter the transfer market in January and sign a defensive midfielder.
It remains to be seen whether or not the typically frugal Frenchman will address that problem in the mid-season window, or alternatively keep faith in Flamini to deputise until the aforementioned stars return to fitness.
