"The run we are on at the moment is a credit to everyone at the club," Smith told MUTV.
"Even if we do not win the title, if we can remain unbeaten until the end of the season, we can look back and say in other years we would have won it. We will try to push on at Crystal Palace on Saturday because you never know what could happen. We still have a chance and as long as that situation exists we will keep battling to the very end."
