Manchester United boss Sir Alex Ferguson admits he messed up after their 2-2 Champions League draw with Porto.
The United boss went ahead with Sunday’s TV clash against Aston Villa, rather than bring it forward 24 hours.
Fergie said: “We showed tiredness because of the gamble I took playing Sunday which was not the best preparation.
“But we faced a situation and we took the best option hoping a European occasion would bring the adrenalin up.”
