Leicester 0-2 Sunderland:Sunderland manager Roy Keane praised the character of his side after an impressive 2-0 win at Leicester in the Coca-Cola Championship.
The Black Cats were made to wait but took the points with two goals in the space of four minutes from Tobias Hysen and David Connolly.
Only Leicester goalkeeper Paul Henderson prevented a much wider margin of victory for the visitors with a string of fine saves, while Sunderland also had 12 shots off-target.
With a number of players out injured, Keane is pleased with the mentality of his squad, who are now three points off the play-offs.
Keane said: "I thought we would get there in the end. We had to be patient and their 'keeper made some great saves.
"We showed great perseverance and desire and I think we could have had a few more goals.
"A few lads haven't been happy with me over the last couple of months because they haven't had the chance to get involved and now is their chance to stake a claim.
"With the injuries, a few have come in and done really well."
Keane is hopeful of some transfer business in the coming weeks but is satisfied with the progress the club has made since his arrival.
He added: "We're doing OK but it was always going to take time. Rome wasn't built in a day as they say but we're heading in the right direction and we're making small steps a day at a time.
"This week there might be one or two coming in and one or two going out.
"We have thought over the last couple of months that we need three or four more (players) but it's easier said than done."
The Foxes, who were booed off, slip to 18th place in the Championship and are six points above the bottom three.
