Manchester United have appointed Walter Smith as assistant to Sir Alex Ferguson until the end of the season.

A United statement read: ‘Walter Smith, one of the most decorated managers in Scottish football history has joined Manchester United until the end of the current season as assistant to the manager, Sir Alex Ferguson.’

Smith’s appointment fills a vacancy that has existed since Carlos Queiroz left the club last summer.

Smith has experience of English football following an undistinguished spell in charge at Everton which ended in the former Rangers boss resigning in 2002.

Sir Alex Ferguson said: “I am delighted that Walter has accepted the chance to join United. There are few people in the game with his experience, knowledge and technical ability.

‘His talent and background will be major assets at such a critical time of the season.

Walter Smith said: “The chance to come to Manchester United is something I couldn’t turn down.

‘There are few bigger challenges in football than helping a successful side sustain their achievements.

‘I have huge admiration for what Sir Alex has achieved at United and IÕm excited to be part of it.”
