United have wiped out an 11-title deficit but, ahead of the Merseysidersâ€™ visit to Old Trafford this weekend, Giggs knows the championsâ€™ work isnâ€™t done.
The 38-year-old told Inside United: "Theyâ€™re a club similar to us with massive history. Weâ€™re the two most successful teams in the country, so we know weâ€™ve got to perform and play well to get anything from any game against them.
"We know weâ€™re in for a tough game. Itâ€™s the club we tried to catch for so long and now weâ€™ve caught them the challenge is to stay ahead."
