Former Ghana international Emmanuel Frimpong has slammed Arsenal manager Unai Emery after his side lost 1-0 to Sheffield United in the English Premier League on Monday night.
Lys Mousset's first-half strike was enough to hand the newly-promoted side all three points at Bramall Lane in their matchday nine fixture.
With an hour left to play, Arsenal were unable to find an equaliser and were left to rue their missed chances at the game.
After the game, Frimpong took to his official Twitter account to express his disappointment in Arsenal's poor performance especially Granit Xhaka.
"Work rate that's all I ask for," wrote the former Premier League footballer. "What does Xhaka give us.
"Change full backs, play holding," he added in a further message. "Look I appreciate chambers is trying his very best as a centre-back but don't you think we need more than that to compete."
The 27-year-old retired from active football in 2019, eight years after making his debut for Arsenal in 2011.
He has previously played for Barnsley, Wolverhampton Wanderers, Charlton Athletic and Fulham.
He also featured for Ufa, Arsenal Tula. Eskilstuna and Ermis.
