Arsenal boss, Wenger has warned his Arsenal players to expect a battle with Diego Costa on Sunday when they face Chelsea.
The Spaniard’s first-half scuffles with Laurent Koscielny and Gabriel led to the Brazilian being sent off for retaliating and his actions drew criticism from all quarters.
Wenger said he expected a tense affair between his club and Chelsea due to the quality of players both teams possess.
He said at a press conference: “We have to be prepared for a battle because Costa gives you a fight. After that, it’s down to the referee.
“We have to focus on our performance. It’s another game where people look at us and see how we behave.
“It will be an intense game, as usual in the Premier League. Overall, I think because of the qualities of the players on the pitch and what is at stake for both teams, it will be a very intense battle.”
Arsenal are top of the table and 19 points clear of Chelsea ahead of the clash at the Emirates Stadium.
