After criticising Stoke for deliberately harming his players at the weekend, Mikael Silvestre is a fresh injury concern after his nose was injured after a challenge from Semih Senturk.
Wenger said: "Was it intentional? I don't know. He rotated his arm. You must ask the player."
Wenger is getting increasingly frustrated as he feels different rules apply to his team.
He said: "You can look at the fair play table. Who is top? Arsenal Football Club.
"We have no lessons to learn from anyone on that front. Look at the team that makes less fouls - it is Arsenal Football Club.
"Who gets the more yellow cards after four or five fouls? Arsenal Football Club.
"Some teams get their first yellow card after 15 fouls. I cannot read the book or something is wrong.
"I'm responsible for the behaviour of Arsenal and we are top. I do not make that table. Instead of having a go at us, people should look somewhere else."
