The England defender played the full 90 minutes of the 5-2 win at Glanford Park. The match was not as one-sided as the scoreline suggested, with the Iron having more possession and creating 22 chances.
"It's always going to be a tricky test coming to places like this," Ferdinand told Sky Sports.
"There was great support tonight from both sets of fans, and it really geed them on in the first-half especially, but when we got our foot back in the game we settled and started playing and put the game to bed."
Tomasz Kuscczak said before the match he would seek a move away from Manchester United if he did not play more first-team football: the stats show he made 10 saves and he was named man-of-the-match by the watching Sky TV people.
That was in contrast to his demeanour during the match, when he lacked composure and flapped at a couple of shots.
"On a few occasions I should have done a little bit better, there were a few shots that were hard to judge," he said.
"It was a busy night, some shots causedme some problems but this is football and we all make some small mistakes."
