Former England boss Graham Taylor recently claimed that Ferdinand had 'lost his legs' after being beaten by Fernando Torres in Liverpool's 2-0 win over United.
It has been a troubled season for the ex-Leeds defender, who missed United's weekend win over Blackburn, with the 30-year-old struggling with injury and a loss of form.
Ferguson is not surprised to see one of his players come under fire, but the vastly-experienced Scot insists the talented centre-back will emerge from his blip as a stronger player.
"In my time here, we have always had one of our star players finding he gets criticised when he has a little blip," explained Ferguson.
"It seems to be part and parcel of being a player at Manchester United. We are all aware of that.
"No player likes to be criticised. We all like to be loved and want arms around our shoulders at times.
"But he will come out of it - there is no question about that. There is no discernible depreciation in his qualities - none at all."
Ferdinand has been hampered by a troublesome calf strain and Ferguson is not confirming whether he will feature in this weekend's clash against leaders Chelsea.
"Playing with injury is not the easiest thing to do, and we are trying to get it right," he continued. "Calf injuries can be troublesome.
"If you don't arrest it and give it proper treatment then you can end up the way we are now, and playing in games when you are not 100 per cent fit.
"It is difficult to say about the weekend. He is doing some good work, and we hope we will see improvement in the two of them."
