Barton was sent off for elbowing Carlos Tevez.
Barton tweeted: "Still don't think it is a sending off. The head was never gone at any stage. Once I'd been sent off, one of our players suggested I should try to take 1 of theirs with me. Never worked but god loves a trier.
"Think a few people are forgetting Tevez started the fracas by throwing a punch to the head."
