Celtic boss Gordon Strachan blamed the Scottish Premier League's under-21 rule for Aiden McGeady failing to make the squad for Saturday's 2-2 draw against Dundee United. Republic of Ireland midfielder McGeady returned this week to training after being suspended following a dressing room bust-up with Strachan.

Strachan pointed to the SPL rule that dictates three outfield players of 21 or under should be in each match-day squad.

Asked the reasons why McGeady was missing, Strachan replied: "The reasons are that I wanted to stay faithful with the squad that played so well in the last two games.

"Also, everyone knows about this under-21 rule which we have complained about consistently since I have come here - as have other managers - but there is no change."
