Wayne Rooney, Javier Hernandez and Jonny Evans will all be back from injury for Manchester United when Norwich visit on Saturday.

Chris Smalling (groin), Nemanja Vidic (ankle) and Tom Cleverly (foot) are still missing but could return after the international break.

Norwich will be without striker James Vaughan as he is set to be out for up to four months with a knee injury.

Centre-back Zak Whitbread is still recovering from his hamstring problem, while on-loan United defender Ritchie de Laet is unavailable against his parent club.

Defenders Elliott Ward and Dani Ayala (both knee) remain out, while young forward Oli Johnson is set for a spell on the sidelines after ankle surgery.

Sir Alex Ferguson has warned his United players to abandon the "cavalier attitude'' that has crept into their game - otherwise they will not win the Premier League.

Ferguson was bewildered by his players' approach against Basle in midweek when

United conceded three goals in the second half and were lucky not to lose before

scoring an equaliser to make it 3-3 in the last minute.

At least Ferguson will be able to pick from a stronger squad when Norwich visit on Saturday, but the United manager's over-riding message is about cutting out

defensive carelessness.

He told a news conference at United's Carrington training ground: "The way we are playing at the moment there's a cavalier attitude to it.

"Maybe people enjoy it but it certainly doesn't win leagues so we have to do better defensively.

"People say our performance on Tuesday was careless and we underestimated our opponents and maybe there's an element of truth in that. I certainly wasn't happy, even in the first half I could smell we were too relaxed and we could have lost three goals in the first half.''

Ferguson pointed out that when Basle scored their second goal, a header by

Alexander Frei, United had only one player in the penalty area challenging the

striker.

He added: "We were too cavalier. On the second goal for instance we had only one defender in the penalty box. Patrice Evra was out wide tracking the boy who crossed it, Fabio was playing outside right, Phil Jones was in centre midfield.

There was only Rio Ferdinand in the penalty box.

"I know it was a fantastic cross but it's an unfair advantage to only have one defender in the penalty box.

"We have to balance attack and defence and that's why it's called a team. A team functions in all parts, understanding each other's parts and we're too cavalier at the moment.''

Ferguson is anxious for his players not to underestimate Paul Lambert's Norwich tomorrow despite the lack of star players in the Canaries squad.

Lambert played for Borussia Dortmund when the Bundesliga side knocked United out of the Champions League in the 1997 semi-finals and went on to become European champions, and Ferguson said his fellow Scot had learned much from his time in Germany.

"Norwich have made a terrific start. You look at Norwich and see full houses every week. There's something happening down there, a vibrancy about the place,'' said the United manager. "I remember Paul as a kid at St Mirren and the next time he faced me, he was at Dortmund when we played the Champions League semi-final.

"He's one of the few Scotsmen to win a European medal outside a Scottish team.

He learned everything there.

"He's started out well at Norwich, they're playing with a great sense of purpose and you can see progress every week. It's been a good move for the lad.''

Ferguson hopes to have Nemanja Vidic, Tom Cleverley and Chris Smalling back from their injuries after the international break but admits that for Vidic and

Cleverley particularly the Liverpool game on October 15 may come too soon.

"Vida and Tom will need to do a lot of good training to be considered for that

sort of match,'' he said.

Lambert maintains Norwich have to aim to upset United at Old Trafford, but knows any game plan can soon be "blown out of the water" by the Barclays Premier League champions.

The Canaries manager took in United's midweek Champions League clash against Basle, and despite United's less-than-impressive defensive display, Lambert knows full well the magnitude of the challenge which awaits his promoted side.

"Some teams are beaten before they even go there, but I will have my own way to deal with that," Lambert said.

"We have to go there with a belief, because if you don't you can get turned over.

"Hopefully you will have a game plan which will try to hurt them, but that can be blown out of the water within minutes.

"You have got to respect what you are up against, you cannot go gung-ho because they will pick you off all over the place.

"You have got to play with your brain a bit and hopefully that is what we will do."

Lambert is in no doubt Ferguson is the "best manager around" having continued to keep United at the top of English and European football during his long tenure.

"It is probably the hardest game you will get, but we have earned the right to play them, and if you don't like playing a game like this, then there is something wrong," said Lambert, who has guided the Canaries up from npower League One in successive seasons.

"I won't need to lift them because the atmosphere and the players they are going to be against will do that for them.

"We will give it a right good go and there have been better teams than us who have gone there and got right turned over, which shows you the magnitude of what we have to face.

"Sometimes upsets can happen and we will try everything we can to win."

Norwich will again be well supported on their travels, with some 3,000 fans expected to make what for many will be the best part of a 10-hour cross-country round-trip.

The Canaries recorded a first away win at Bolton last weekend, which they followed up by beating Sunderland 2-1 at Carrow Road on Monday night.

Most of the away supporters will be making the journey to Old Trafford more in hope than genuine expectation.

Lambert, though, insists his squad must give a good account of themselves on the pitch.

"I hear all the time it is a great day out, but it is only great if you are doing all right, not if you are getting smacked six or seven nothing," he said.

"I don't buy into it is a lovely day out for the supporters.

"It is only if you are giving a right good go at it."

Striker James Vaughan is set for an extended spell on the sidelines after damaging knee ligaments against Sunderland.

Having just returned from a pre-season injury on his other knee, Lambert feels for the summer signing from Everton.

"James is going to be out for a considerable time which is a blow because I thought he was looking really good," the Norwich manager said.

"It is a pity for himself because he had worked hard to get back."
