Davide Santon says Newcastle United players know fans deserve better after defeat to Southampton.
Santon insists they must ensure that their campaign is not allowed to fizzle out.
He said: "It doesn't have to be like this. We have to put in good effort in every game until the end of the season.
"Even though we know we cannot get a place in Europe or any competition now, we have to still play our best - that's what we didn't do (at St Mary's)."
