Manchester United boss Sir Alex Ferguson admits he may've got his tactics wrong at home in Europe this season.

After Thursday night's 3-2 defeat to Athletic Bilbao, Ferguson feels a change in attitude is now required.

"We have had a bad year in Europe," he said.

"We conceded three against Basel, two against Benfica, another three against Bilbao and two to Ajax. That tells its own story.

"Maybe it is just one of those years where we are having to restock and assess how we should approach games at home."
