Newcastle's summer signing from Hull was a target for criticism despite his side's win against Barnsley.
Dropped for Saturday's win against Brentford, having failed to score in any of his eight Newcastle appearances, Diame was restored to Rafa Benitez's starting eleven at Barnsley on Tuesday night.
And though the team as a whole impressed in South Yorkshire - winning 2-0 to leapfrog Norwich at the top of the Championship - Diame continued to struggle.
The Senegal international, it seems, was unable to silence his detractors, who were out in force on Twitter both during and after the match.
And their feedback doesn't make for pleasant reading if your name's Mo Diame... or Shola Ameobi and Moussa Sissoko - two Newcastle players of recent past - for that matter.
Would rather of signed Stevie Wonder than Mo Diame... just saying #NUFC— Adam (@Adam9nufc) 19 October 2016
Diame just doesn't cut it for me. Certainly not the player I thought he was, very poor again tonight! #NUFC— Ditchy (@thetoonreview) 18 October 2016

By the way Hull have 100% robbed us for Diame. #nufc— alisha henry (@alishahenry90) 18 October 2016
Dwight Gayle saves Twitter from a Mo Diame meltdown probably #nufc— Ian Nelson (@inelson77) 18 October 2016
Diame is definitely sissoko and shola rolled into 1— insane in the brain (@kevbutler87) 18 October 2016
What is Diame bringing to the team...— NUFC Global (@NUFC_Global) 18 October 2016

Two goals from Dwight Gayle, his 10th and 11th of the campaign, were enough to see off Paul Heckingbottom's side and leave Newcastle looking down on the rest of the division for the very first time.
And the new leaders host Ipswich Town on Saturday at St. James' Park.
