He would not consider the prospect of the match being his last as Blues boss, with the FA Cup and Europa League still targets too.
"'If' is not a point for me now," he said.
"I'm quite positive we can get a result, finish in the top three, top two. We will see. That is my feeling.
"Realistically, it won't be easy. Manchester City are a good team and they have good players. They can keep winning games and it will be difficult.
"But you never know in football. Top three, top four. That is a target.
"It's very clear still we have a lot of good chances. We will try to do our best in every competition.
"West Brom will be the first one. After that we'll try to progress in the Europa League and FA Cup. Every game is important. We want to win every game."
