Sir Alex Ferguson has called on Manchester United to repeat their performance against Barcelona from last season when they host Internazionale on Wednesday night.
United will go head-to-head with Jose Mourinho's Italian champions at Old Trafford in the second leg of a last 16 Champions League tie with the scores deadlocked at 0-0 following the first encounter two weeks ago.
The tie mirrors last year's semi-final against Barcelona where the Red Devils failed to score an away goal before securing a 1-0 home win over the Spanish giants.
And Ferguson wants a repeat of the performance which saw his side book their place in the Moscow final where they were ultimately crowned champions of Europe.
"You can never be over confident in this position simply because an away goal can be a severe setback," warned the veteran Scot.
"That was the situation when we played Barcelona. What we required that night was magnificent concentration and really good focus in our game. We managed to get through because of both those factors."
Meanwhile, Ferguson is predicting a titanic tussle against the Italian champions.
He added: "When you play an Italian side you have got to be at your best. Their record over the years has been fantastic.
"AC Milan have won the European Cup seven times - all in the modern era - which I believe makes them the most successful side because Real Madrid won their first five when European football was just beginning.
"Inter Milan have every right to go into the match thinking they can win. They are seven points clear at the top of their league and have a lot of experience.
"We expect a tough game but they should expect one as well."
