Le Guen replaced in-form keeper Alan McGregor with Lionel Letizi

Paul Le Guen has refused to be drawn on the controversial decision to replace goalkeeper Alan McGregor following a 1-0 defeat at home to Caley Thistle.

"I don't want to speak about that, it's between us and it's better like that," he told BBC Sport.

"It is my job to choose in relation to what I think. It is not my main thinking today.

"My main thinking is about our game, and the way to improve it, because we need it."

Le Guen was unhappy at the quality of the play during the 1-0 defeat at Ibrox.

FANS' FORUM Yesterday's booing of Letizi was unacceptable, that is not the Rangers way. Yes, I would rather have seen McGregor in, but Le Guen's job is to pick the team, not ours Rangers51 - Rangers board Fans Forum: Have your say

"It's a bad result," he said. "It's a bad performance and I have the feeling we could have played for three hours without scoring a goal. That's why I'm very disappointed.

"We must improve, otherwise it will be difficult. We lack inspiration, we lack wingers and we lack speed.

"And, when you lack such qualities, it's difficult to score.

"We had some very good games at the beginning of the season, but today we must recognise was most poor."
