Leicester City 1-0 Sheffield United

Leicester can "move on" from the Riyad Mahrez transfer saga after the Algerian helped them reach the quarter-finals of the FA Cup, says manager Claude Puel.

Mahrez, who was back in the side after missing 10 days of training when a proposed move to Manchester City did not materialise, set up Jamie Vardy's goal in a 1-0 win over Sheffield United.

He left the field to a standing ovation when replaced by Matty James in added time.

"The most important thing in the game was the fans supported Riyad, and when I replaced him it was a good feeling with the fans," said Puel.

"It's important to stay united about this.

"The situation is behind us, it's important to look forward. Now we have two home games in the Premier League and it's important to get the support of the fans."

Leicester had to work hard to break down a well-drilled Blades defence, and the Championship visitors went close through Enda Stevens and George Baldock.

But their Premier League hosts dominated possession, and Vardy had a second effort ruled out for offside.

Leicester, who are now unbeaten in seven home games, always looked most likely to score first, but only kept their advantage thanks to Kasper Schmeichel's fine diving save from Baldock.

The Foxes will discover their last-eight opponents on Saturday at 20:00 GMT.

Mahrez's name received the loudest cheer when the Leicester team was read out before the match, showing the Foxes faithful are a forgiving lot.

The Algerian was back in the starting line-up 16 days after a potential deadline-day move to Manchester City ended in disappointment for him.

It was the second high-profile occasion he had tried to leave Leicester, and the second time their fans had to decide how to respond.

Their support before kick-off will have eased any nerves the 26-year-old harboured, and he replied with an assured performance, including creating the goal for Vardy.

He showed little sign of rust, making four key passes - more than any team-mate - and did enough to suggest he has knuckled down again.

With that issue resolved, Puel wants "conviction and desire" from all of his players on the run-in.

"There are 11 Premier League games left, and we have the FA Cup," he said. "It's a crucial competition for us."

United boss Chris Wilder's options were limited by a combination of injuries, suspensions and cup-tied players.

The Blades, who fielded an under-strength side in their 4-1 defeat by Leicester in the Carabao Cup earlier this season, again had an unfamiliar look, with six changes from their win over Leeds.

So it was to their credit that they produced a sterling defensive performance, exemplified by centre-back Jack O'Connell.

For more than an hour they frustrated a team able to call on an England striker, and other attacking talents of the calibre of Mahrez and Kelechi Iheanacho.

They had just 31% possession but still gave the Foxes a couple of scares, including when Stevens' goalbound shot was diverted behind by Harry Maguire.

If being thwarted by one of their ex-players hurt, it paled in comparison to the pain they will have felt when former Sheffield Wednesday youth-teamer Vardy hit the net.

But the travelling fans can be proud of a spirited display, which underlined the strength in their squad as they fight for a place in the top flight.

"We gave a good account of ourselves, but we are disappointed," said Wilder.

"We have performed great all season, the consistency levels have been great. To not be overrun here gives us great heart, and we need a great run in the league, which that has to be our priority.

"All I ask is we always leave everything out there on the pitch, and we need to push on now."

Leicester host Stoke City in the Premier League on Saturday, 24 February (12:30 GMT), while Sheffield United host QPR in the Championship on Tuesday, 20 February (19:45 GMT).
