United may have emphatically seen off Arsenal in the Champions League, but Rio Ferdinand says the Reds will not be underestimating the Gunners in Saturday's league meeting.
Sir Alex's men need just one more point to secure an 11th Barclays Premier League title meaning a win or a draw will suffice at Old Trafford. Ferdinand insists United will have to work hard to gain the solitary point required against a Gunners side with a score to settle.
"Our performances in both legs of the semi-final were two of the best of the season," the defender told United Review. "But it can sometimes be a dangerous situation when you beat a team fairly convincingly and play them again soon after because they’ll probably feel they have something to prove.
"We can't allow them to do that and must focus on getting the result we want to win the title."
