|1/10||Mesut Ozil is 21/2 with BetVictor to open the scoring in Arsenal v Chelsea|
Chelsea could leapfrog Arsenal with a win at the Emirates Stadium but Mourinho concedes Ozil, who has scored five goals and registered nine assists in all competitions this term, will be a constant thread to his side.
"I know his strong points. Not the weaknesses," Mourinho told reporters.
"I think I know how to try to stop him to be in the game [for] 90 minutes, with 90 minutes of direct influence.
"But it's impossible to stop him for 90 minutes, because these kind of players they will have always a moment or a couple of moments where you cannot stop them and they end up showing why they are so good.
"To stop him completely, I don't believe we can."
