"We will keep fighting and putting the pressure on Manchester United," said Kuyt.
"It was a pity that we didn't beat Arsenal on Tuesday because I thought we played really well, only we made too many mistakes, but sometimes that happens.
"We have to move on now to what's in front of us. We will try to win our games and hopefully they will lose some points.
"I've seen some strange things happen. We could still do it."
