Former Arsenal midfielder Emmanuel Frimpong embarked on an X-rated tirade on Twitter last night, blasting his old manager Arsene Wenger for his failure to strengthen his squad in the necessary positions during the summer transfer window.
The Ghana international's explosive social media comments were made on Wednesday evening while the Gunners were losing away at Anderlecht in the Champions League.
Arsenal actually completed a late turnaround with two last-gasp goals from Kieran Gibbs and Lukas Podolski, but by that point the 22-year-old's forthright views had already been posted.
Frimpong is no stranger to controversy when it comes to expressing his outspoken opinions online, and the midfielder - who now plays for Russian side FC UFA - has been caught up in a number of unsavoury altercations before.
However, his latest outburst is perhaps the most critical he's been of Wenger, slamming the frugal Frenchman's approach to recruitment, which he feels has left the squad short on options. His statement could also be perceived as a plea to make more signings when the transfer window reopens in January.
Reading between the lines it suggests that Frimpong doesn't rate German centre-back Per Mertesacker, calling for a new player to partner Laurent Koscielny at the heart of Arsenal's back line.
It's true that the Gunners are short on central defensive options ever since Thomas Vermaelen's departure to Barcelona, and that has been highlighted by Wenger's decision to play Calum Chambers - the relatively inexperienced summer signing from Southampton - in the middle at times this season.
Frimpong wasn't finished there, though, as he tried to justify his claim, suggesting that many of Arsenal's current crop of players possess very similar attributes.
The African managed to bite his tongue by not directly disrespecting any individual players, but Chilean playmaker Alexis Sanchez could be forgiven for not taking too kindly to Frimpong's comments after suggesting that the money paid to Barcelona to bring him to the Emirates Stadium could've been invested better elsewhere in other areas of the team.
Wenger did admit at Arsenal's recent AGM that he made a mistake not signing a central defender in the summer, but despite that he's unlikely to take much notice of Frimpong's view having already washed his hands of him last year.
