'It is for Chelsea to throw away now,' Keane told MUTV.
'On an off day they might drop a few points but other teams will have to win three or four games just to catch them up. There is no doubt about it, Chelsea are in a great position. They are playing well and deserve great credit but it would be nice to put them under pressure.'
"But lots of those players have not been in this position before, that's why it is important to put them under pressure. They have answered all the questions so far but we will see what happens from now."
"It is no good the gap still being 11 points going into the last month or two," said Keane. "People have been critical of us all this season. We haven't been playing as well as we could - as Arsenal have recently. We must reduce the gap before they come to Old Trafford so we can see what their temperament is like."
