The Scot believes the changes will lead to "boring" games since teams will be defending more
Bobby Williamson believes abolishing the away goal rule is a wrong move and will encourage clubs to defend more, especially away from home.
On June 24, Uefa confirmed the away goals rule will be abolished from European competitions, with the change being put into place in time for the 2021-22 season.
The away goals rule has been used for over half a century but will no longer be used to decide knockout matches in Uefa club competitions, including the Champions League and Europa League.
