Dimitar Berbatov insists Manchester United will stay strong as they bid to recover from their mini-slump.
After successive Barclays Premier League defeats to Liverpool and Fulham, United host Aston Villa on Sunday - by which time they may have been replaced at the top of the table by Rafael Benitez's men, who are at Craven Cottage themselves 24 hours earlier.
Nine thrives: Dimitar Berbatov is eying glory with Manchester United
Anderson was forced to pull out of World Cup duty with Brazil after picking up a thigh injury, and Berbatov is also struggling to be fit after suffering an ankle problem at Fulham which ruled him out of Bulgaria's draw with the Republic of Ireland last weekend.
However, the former Tottenham striker is not getting too downhearted - and insists the atmosphere within the Old Trafford camp is still good.
'We are a strong team and we all support each other,' he told MUTV. 'We know how to react after defeats.
'International breaks are sometimes difficult, because you have two games and you come back and can be a little bit tired; then you have a game immediately after that. But that's our job - there's no need to complain.'
Although they appear to be in turmoil as they try to resist Liverpool's recent rally, United are still well placed to complete an unprecedented Quintuple.
The loss of Anderson would be a blow if he fails to recover, considering Ferguson wanted all his squad back before considering his options for the double-header with Villa and then Porto in the Champions League.
But Berbatov still feels there is plenty of reason to look on the bright side.
'Everything is possible,' he said. 'If you believe and have faith, and you really want it, it can happen.
'We need to believe in our quality and our ability. I think the gaffer will know the right encouragement to give us to prepare for the games we have. We will stay strong to the end.'
Most of the United players have the experience of winning major trophies to fall back on - but not so Berbatov, who was an onlooker last month as his team-mates overcame his old club Tottenham to win the Carling Cup. It was a taste of glory the 27-year-old is anxious to enjoy himself.
'I told the boys in the dressing room, "you have already won the Champions League and Premier League",' he said.
'The only one who hasn't is me. I really want to win those trophies so I can say to the other players "I am one of you".'
