The Pilgrims lost for the second home game this season as the Chairboys rattled in three late goals leaving Sheridan to do the talking for his under-performing side.
Sheridan told the Plymouth Herald: "I get annoyed with people talking when we win two or three games. It does get to me.
"I will do all the talking. We are not a good enough team to go out and say 'we are doing this and we are doing that'.
"It's only me who should be talking really, for all of them, and I mean that. I know what's around the corner so I have got to stay focused and not let them switch off.
"I want them to be bad losers. I really do.
"When they are losing I want them to make it as difficult as possible for the opposition and we did not make it difficult for them (Wycombe)."
