Michael Carrick believes Manchester United have work to do in their UEFA Champions League clash with AC Milan despite a first leg success.
The Red Devils are in pole position to secure a place in the quarter-finals of the competition following a 3-2 win in the San Siro.
United had led by two goals thanks to Wayne Rooney's brace, but Clarence Seedorf's late effort means Milan's task in Manchester is not an impossible challenge.
Carrick, who was sent off late on in the first leg and will miss the Old Trafford encounter, admits they are favourites, but has conceded it is important they start right on home soil.
"You would probably say we are favourites to go through but we know how important the start of the next game is," said Carrick.
"If we can get the next goal we will be in a great position but as things stand at the moment it's still in the balance.
"We have got to make sure we perform again at Old Trafford."
United got off to the worst possible start with Ronaldinho stroking home early on, but the visitors recovered from the knock to turn things around.
Carrick believes Sir Alex Ferguson's men are in red-hot form and that they could and should have scored more than the three they plundered.
"We are playing well at the moment and scoring a lot of goals," he continued. "Even after the bad start last night we were still confident that we could get a grip of the game.
"We played some good stuff in the second half and could have scored more. We were the ones looking more likely to increase our lead towards the end.
"It didn't quite work out like that but we were reasonably pleased with the way it turned out."
