• Old Trafford fear factor dissolving, says Morten Wieghorst
• David Moyes admits he is worried by run of home defeats
The Swansea assistant manager, Morten Wieghorst, has claimed David Moyes's appointment as the Manchester United manager has led to "insecurities" that the Welsh side will prey on at Old Trafford on Saturday, with the Dane stating the champions' stadium has shed its fear factor following United's five defeats there this season.
United have lost their last three matches which includes being knocked out of the FA Cup by Swansea in Sunday's third-round tie.
That result, and the dismal league form that has left Moyes's side 11 points behind the leaders, Arsenal,has persuaded Wieghorst that Michael Laudrup's team can take advantage.
"They have already lost five home games," he told Denmark's Jyllands-Posten newspaper. "There is no doubt that this fear factor that United have had at Old Trafford is slowly disappearing and let us see if we can use that now that we have a good win there in our heads."
Regarding Moyes's appointment, Wieghorst said: "We know that there develops a bit of nervousness when a big club goes through a period with a new manager and when the victories aren't forthcoming. There will be some insecurities in a team like that, even if they have very good players, and we will try to take advantage of that. There will be 75,000 people there and every now and then you can catch a big team at a good time."
Wieghorst pointed to Swansea's 3-0 dismantling of Valencia in an Europa League group game at the Spanish club's ground in September to emphasise his point. "We saw that when we played Valencia," he said. "We played them at a good time when the atmosphere [in their stadium] was against the team and then the crowd can quickly turn against their own team if there is a setback. And that is exactly what we will try to take advantage of at Old Trafford."
Moyes attempted to brush off Wieghorst's claims by stating that the media may be interpreting comments slightly differently to how they were intended. "Everybody can have their own opinion," he said.
"You all are, you people, at the minute and probably taking some of the words out of a bit of context. But we have lost a few games at home and that's why people are saying these things. We have to try to do something about it."
In addition to the Swansea defeat, United's losses at Old Trafford have been to West Bromwich Albion, Everton, Newcastle United and Tottenham Hotspur with four of these coming in the four weeks leading up to the victory by Laudrup's side in the FA Cup.
Moyes admitted this was a concern. "It is, of course it is. You cannot turn around and say you are not worried about it. It is a concern, so we have to get our home form right because in this position, people will always have an opportunity to find some form of criticism or find a weakness."
