Smalling convinced Man Utd inconsistency due to unsettled XI
Smalling concedes the constant changing has been disruptive.
"Nobody could have foreseen all the injuries we have had," said the England defender.
"At the start of the season we had good numbers and good quality.
"With so many injuries, the form was bound to dip once or twice. But we are all pulling together and there have been plenty of good results."
