It leaves Danny Rohl’s Wednesday five points from safety in the Championship with games running out.

Enzo Maresca’s side had the game won by half-time and are now 14 points clear of third-placed Southampton as they close in on promotion back to the Premier League.

Vardy, who was released by the Owls for being too small as a teenager, also played a part in the opening goal for Abdul Fatawu after four minutes.

Vardy started a game for the first time in more than two months and, coincidentally, the last Championship game he was on from the start was against Wednesday.

But this was a genuine team display with threats from all over the pitch in a commanding performance against Danny Rohl’s struggling side.

Leicester took an early lead after a mix-up in the visitors’ defence.

Goalkeeper James Beadle’s short pass put Will Vaulks in trouble with Dennis Praet close by. The ball fell to Kieran Dewsbury-Hall who delivered a cross meant for Vardy – but his step-over allowed the ball to go through for Fatawu and he tapped into an empty net.

Wednesday struggled against Leicester’s slick style of play with Harry Winks, Vardy and Dewsbury-Hall all causing problems.

On the half-hour, Dewsbury-Hall twisted and put in a cross which defender Wout Faes could only hook over the crossbar.

But Leicester extended their lead nine minutes before half-time when a long ball from Faes found Dewsbury-Hall and he neatly set up the chance for Vardy to score with an angled drive.

It was his 11th goal of the season and made him Leicester’s top scorer.

The Owls briefly threatened to pull a goal back when Djeidi Gassama’s long-range shot was saved by Leicester goalkeeper Mads Hermansen.

Wednesday substitute Anthony Musaba then sent a shot inches past the far post as the game passed the hour mark.

Vardy received a standing ovation when he was substituted with 10 minutes to go.

Leicester were able to play out the final minutes under no pressure, although there were some encouraging signs for Rohl in the second half.
